Overview
Lattice MachXO2-4000HC is a CPLD chip, that is used in TEB0912 board as a system management controller. The system controller implements power management same as power sequencing, monitoring of input current and regulator outputs . Rather than power management is the system controller responsible for reset generation, zynq initial configuration, communication between temperture sensors and FPGA. System controller contains of some additional features same as watchdog timer, i2c interface, CAN bus and SMbus. The firmware of CPLD contains of various subsystems same as i2c master and i2c slave subsystems. I2c master reads the data of current sensor and 7 temperature sensors , that measure the temperature of DC-DC converter chips. I2c slave is responsible for communicating with FPGA to write the measured data in debouncing the power button and displaying the power status with LEDs. The JTAG and UART interfaces are routed in the firmware of CPLD from FTDI chip to FPGA.

Functional Description
JTAG
JTAG signals routed directly through the CPLD to FPGA. Access between CPLD and FPGA is be multiplexed via JTAGEN pin of CPLD (B30) (logical one for CPLD, logical zero for FPGA).

Boot Mode
TEB0912 supports JTAG, QSPI and SD card boot modes. Boot mode depends on the logic state of S2 dip switch pins that are connected with FPGA boot mode configuration pins.

Power
In this board the CPLD is responsible for controlling and monitoring of power supply of the board. There are various DC-DC converter or regulators , one input current sensor and seven temperature sensors. To control every converter chip or regualtor monitors CPLD power good outputs of regulators or DC-DC converters continuously to avoid over-voltage in the power system. System controller reads the measured temperature of all temperature sonsors continuously to avoid over-temperature in regulators or DC-DC converter chips.
