12.10 - Port 8
If this 8-bit port is used for general purpose I/O, the direction of each line can be configured via the corre-
sponding direction register DP8. Each port line can be switched into push/pull or open drain mode via the
open drain control register ODP8.
P8 (FFD4h / EAh)
DP8 (FFD6h / EBh)
ODP8 (F1D6h / EBh)
12.10.1 - Alternate Functions of Port 8
The 8 lines of Port 8 (P8.7...P8.0) serve as capture inputs or compare outputs (CC23IO...CC16IO) for the
CAPCOM2 unit.
The usage of the port lines by the CAPCOM unit, its accessibility via software and the precautions are the
same as described for the Port 2 lines.
As all other capture inputs, the capture input function of pins P8.7...P8.0 can also be used as external
interrupt inputs (200 ns sample rate at 40MHz CPU clock).
The Table 20 summarizes the alternate functions of Port 8.
