The debug board is an integral part of the MXC 3-stack(PDK)
platforms, it can be attached or removed from the peripheral
board. On debug board, several debug devices(ethernet, UART,
buttons, LEDs and JTAG) are implemented. Between the MCU and
these devices, a CPLD is added as a bridge which performs
data/address de-multiplexing and decode, signal level shift,
interrupt control and various board functions.
