Notes (Table 3.1A):
1. Writes to these registers may have an adverse effect on
module operation. Use the Port 7 Write Mask to prevent
writing to these registers.
2. The IOS will respond to addresses that are “Not Used” with
an active IOS module acknowledge (ACK*). The board will
return “0” for all address reads that are not used or reserved.
3. Writing four unique bytes (07H, 0DH, 06H, and 12H) to port 7,
in consecutive order, will switch to Enhanced Mode. Perform
this operation after reset or power-up with interrupts disabled.
Do not read or write to any other port between writes.
4. The upper 8 bits of these registers are not driven and pull-ups
on the carrier data bus will cause these bits to read high (1‟s).
