RGPIO Master is a 32Bit Remote GPIO Interface to talk with FPGA over 3 lanes.

LED	Description
ULED1	blink when VCCIO(VIOTB/VADJ) is disabled else on when VADJ on PCB REV05- or I2C Control or off when VADJ on PCB REV06+ S4 Control
ULED2	I2C control mode when RGPIO Bus is not active else RGPIO Bus Pin 1
ULED3	UART to Module activity when RGPIO Bus is not active else RGPIO Bus Pin 2
ULED4	UART to FTDI activity when RGPIO Bus is not active else RGPIO Bus Pin 3
ULED5	BOOTMODE (on Flash, off SD) when RGPIO Bus is not active else RGPIO Bus Pin 4
ULED6	CM2 when RGPIO Bus is not active else RGPIO Bus Pin 5
ULED7	X6 when RGPIO Bus is not active else RGPIO Bus Pin 6
ULED8	Y6 when RGPIO Bus is not active else RGPIO Bus Pin 7
