LLOCATION
Appendix D provides the pin and block associations on the Rabbit
RIO chip with their corresponding I/O on the BL4S100 boards.
The main shared resource within the RIO chips are the counter/timer
blocks — the RIO chip has eight counter/timer blocks. A given
block is defined by 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 BL4S100 board.
