12.11.1 - Alternate Functions of Port 8
The 8 lines of Port 8 serve as capture inputs or as
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.

Alternate Function
As all other capture inputs, the capture input
function of pins P8.7...P8.0 can also be used as
external interrupt inputs (200ns sample rate at
40MHz CPU clock on PQFP144 devices and
250ns sample rate at 32MHz CPU clock on
TQFP144 devices).
The Table 25 summarizes the alternate functions
of Port 8.
