12 - PARALLEL PORTS
12.4 - PORT1
The two 8-bit ports P1H and P1L represent the higher and lower part of PORT1, respectively. Both halves
of PORT1 can be written (via a PEC transfer) without effecting the other half.
If this port is used for general purpose I/O, the direction of each line can be configured via the
corresponding direction registers DP1H and DP1L.
P1L (FF04h / 82h)
P1H (FF06h / 83h)
DP1L (F104h / 82h)
DP1H (F106h / 83h)
12.4.1 - Alternate Functions of PORT1
When a demultiplexed external bus is enabled, PORT1 is used as address bus.
Note: Demultiplexed bus modes use PORT1 as a 16-bit port. Otherwise all 16 port lines can be used for
general purpose I/O.
The upper 4 pins of PORT1 (P1H.7...P1H.4) are used as capture input lines (CC27IO...CC24IO).
During external accesses in demultiplexed bus modes PORT1 outputs the 16-bit intra-segment address
as an alternate output function.
During external accesses in multiplexed bus modes, when no BUSCON register selects a demultiplexed
bus mode, PORT1 is not used and is available for general purpose I/O.
