2.10.6 System services slot signals

On all slots, TDO is always out of the sliceKIT core board, TDI is always in to the
core board.
MSEL, TCK, TMS, RST_N are all inputs to the core board from the Chain connector
and outputs from the core board on the Square slot.
DEBUG is bidirectional.
PRSNT is used on the Chain connector to detect it is plugged into the Square slot of
another core board. This signal is used to switch JTAG and CLK sources. Similarly,
PRSNT_N is used on the Star slot to detect another core board is connected. This
signal is used to switch the JTAG chain signals.
CLK and RST_N are inputs to the core board from the Chain connector and output
from all slots.
