Port 8 Data Direction Register (P8DDR)
P8DDR is an 8-bit write-only register that can select input or output for each pin in port 8.
Bit
Modes
1 to 4
Modes
5 to 7
Modes 1 to 6 (Expanded Modes)
When bits in P8DDR bit are set to 1, P8
P8DDR are cleared to 0, the corresponding pins become input ports. In modes 1 to 4
(expanded modes with on-chip ROM disabled), following a reset only CS
three pins are input ports. In modes 5 and 6 (expanded modes with on-chip ROM enabled),
following a reset all four pins are input ports.
When the refresh controller is enabled, P8
refresh controller is disabled, P8
setting. For details see table 9.15.
