Appendix D provides the pin and block associations on the Rabbit
RIO chips with their corresponding I/O on the BL4S200 boards.
The main shared resource within the RIO chips are the counter/timer
blocks — each RIO chip has eight counter/timer blocks. The
BL4S200 boards have three RIO chips, which gives a total of 24
blocks. A given block is defined by both the RIO number and
the block number. The tables in this appendix provide a quick
reference of which block is used by each input and/or output pin
on the BL4S200 board.
