USR3	Description
OFF	JTAGMODE = '0' → JTAG routed to module FPGA
ON	JTAGMODE = '1' → Access to CPLD of module

JTAG

In normal mode JTAG is routed directly to the module. JTAGEN set carrier board CPLD into the chain for firmware update. Set S3-3 (ENJTAG) to OFF to get access to carrier CPLD. JTAGMODE set module CPLD into the chain for firmware update. In normal mode JTAG is routed directly to FPGA. To access CPLD of TE0715 JTAG port must be routed to special pins same as NOSEQ pin. Therefore in PCB REV04 or later USR0 is used to access CPLD of TE0715 module. For PCB REV03 CM0(S3-2) and CM1(S3-1) dip switches will be used for this purpose. In this case user must be careful because these dip switches are used to select FMC_VADJ output voltage too.

Warning

title	Warning

For some 4x5 modules if FMC_VADJ voltage is set incorrectly, the FPGA can be damaged !

I2C to GPIO

I2C to GPIO is a subsystem in firmware of CPLD that provides an i2c interface that writes received data to GPIO_output 8 bit registers or reads 8 bit GPIO_input registers and send read data to i2c bus.

On-board LEDs

LED glows depending on various signals in firmware or pins of CPLD. Additionally to test I2C to GPIO output registers S1 push button can be used to display GPIO_output[7:0] register on LEDs. If S1 is pushed, ULED1 to ULED7 display GPIO_output[7:0] register. PHY_LED1/PHY_LED1_A and PHY_LED2/PHY_LED2_A are RJ45 connector right LED and RJ45 connector left LED respectively. These LEDs are using to display states of PGOOD, NOSEQ and EN_FMC signals.

In PCB REV04 USR1 is used to change NOSEQ signal, if no access to TE0715 CPLD is active (USR0 = OFF)
In PCB REV04 USR2 is used to change PGOOD as Boot Mode, if no access to TE0715 CPLD is active (USR0 = OFF)
In PCB REV04 USR3 is used to change JTAGMODE signal of CPLD of module. USR3 = ON --> Access to FPGA , USR3 = OFF --> Access to CPLD of module
In PCB REV03 CM0(S3-2) and CM1(S3-1) dip switches are used to access to CPLD of TE0715 or other modules.
