Overview
A Lattice XO2-1200 CPLD (U19) is used as a System Management Controller (referred to as SC in the manual). The SC is responsible for power sequencing, reset generation and Zynq initial configuration (mode pin strapping). Moreover, some on-board ICs are connected to the SC that provides level shifting. The SC wakes up when the 3.3V input power rises above 2.1V (VIN voltage is not needed). The SC can turn on or off all of the other supplies on the module (except in no power sequencing mode when the 1.0V and 1.8 V supplies are forced to start immediately when power is applied to the module).
System Controller (SC for short) was designed to allow ZYNQ PS system to access module special functions as early as possible without reducing the number of MIO pins that are fully user configurable.This early communication channel is done using MIO52 and MIO53 pins that are used also as Ethernet PHY management interface for the on-board Gigabit PHY. In order to simplify the boot process and reduce the number of time the PS peripherals need to be configured or re-initialized SC uses the same protocol on MIO52/MIO53 as the Gigabit PHY itself. This means that FSBL Configures all peripherals to their final function, allocating MIO52 and MIO53 as Ethernet MDIO Interface. SC Controller appears as "Virtual Ethernet PHY" on the MDIO bus of PS Ethernet 0 Interface. This interface is already available when Zynq PL Fabric is not configured. It would have been possible to use I2C Protocol on MIO52/MIO53 but in such case some multiplexing would be needed to choose between two protocols, also it would be needed to change the Peripheral mapping after first init by the FSBL. For use cases where Ethernet PHY on TE0720 is not used at all, it is still possible to configure SC with design that implements I2C Protocol on MIO52/MIO53 pins.For most use cases the only need to use this interface is access to MAC Address info, this is normally done by u-boot loader that fetches the MAC Address bytes and sets its environment variables accordingly. Linux image will then also be started so that the MAC Address from EEPROM is used for Ethernet 0 Physical interface.

RESIN | JM2-Pin 18 | input, weak pull-up | Reset input | IO | Active Low Reset input, default mapping forces POR_B reset to Zynq PS |
NOSEQ Pin
This is a dedicated input that forces the module's 1.0V and 1.8V supplies to be enabled if high. This pin has a weak pull-down on the module. If left open the module will power up in normal power sequencing enabled mode. This pin is 3.3V tolerant. This pin is also connected to the System Management Controller. The SC can read the status of this pin (that is it can detect if the module is in power sequencing enabled mode). The SC can also use this pin as output after normal power on sequence. Please check the SC description for the function. SC rev 0.02 maps Ethernet PHY LED0 to NOSEQ by default (the mapping can be changed by software after boot).
No Sequencing mode
If the module is powered from a single 3.3V supply and power sequencing is disabled, then NOSEQ pin should be powered from the main 3.3V input. That is VIN, 3.3Vin and NOSEQ should all be tied together to the input 3.3V power rail. Sequencing mode should not be used if VIN is not 3.3V.
Normal mode
For normal operation leave NOSEQ open or pull down with a resistor.
Normal mode with user function on NOSEQ
NOSEQ can be used as an output after boot. NOSEQ must be low when 3.3V power is applied to the module. Common usage is an LED connected between NOSEQ and GND.

It is available to the user only after the power supplies have stabilized and the POR reset to the Zynq is released.

LED3 Green (FPGA Done)
This green LED is connected to the FPGA Done pin which has an active low state. As soon as the Zynq is powered and the 3.3V I/O voltage is enabled, this LED will illuminate. This indicates that the Zynq PL is not configured. Once the Zynq PL has been configured the LED will go off.
During normal operation when the Zynq PL has been configured, the LED can be controlled from the FPGA fabric. Control of the LED in a user design requires the use of Xilinx startup primitive rather than a normal I/O primitive. If the startup primitive is not used then the LED will go off after configuration and remain off irrespectively of the user design. This LED can not be controlled by the SC.

WEEE
Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).
Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
