2x5 Timing Header
The FPGA board has one 2x5 GPIO header J5 for expansion function. The pin-out of
J5 is shown in
. GPIO_P0 ~ GPIO_P3 are bi-direction 1.8V GPIO.
GPIO_CLK0 and GPIO_CLK1 are connected to FPGA dedicated clock input and can
be configured as two single-ended clock signals or one differential clock signal. Users
can use Terasic defined RS422-RJ45 board and TUB (Timing and UART Board) for
RS422 and external clock inputs/UART applications.
shows the mapping of the FPGA pin assignments to the 2x5 GPIO header.
