- OK, I added Peter's version of the state table, and it works OK for

- new state table. His changes to my state table are pretty minor in
- terms of total transitions, but Peter feels that his version fixes

-
- I added the bit count into the table, reduced RESET column to 7 bits from 8.

- state specific comments:
- ------------------------
- *->RESET tried the 5 bit reset and it gave me problems, 7 bits seems to
- work better on ARM9 with ft2232 driver. (Dick)
-
- RESET->DRSHIFT add 1 extra clock cycles in the RESET state before advancing.
- needed on ARM9 with ft2232 driver. (Dick)
- (For a total of *THREE* extra clocks in RESET; NOP.)
-
- RESET->IRSHIFT add 1 extra clock cycles in the RESET state before advancing.
- needed on ARM9 with ft2232 driver. (Dick)
- (For a total of *TWO* extra clocks in RESET; NOP.)
-
- RESET->* always adds one or more clocks in the target state,
- which should be NOPS; except shift states which (as
- noted above) add those clocks in RESET.
-
- The X-to-X transitions always add clocks; from *SHIFT, they go
- via IDLE and thus *DO HAVE SIDE EFFECTS* (capture and update).
