9.6.2.11 I/O – Port A, B, E

Ports A, B and E have the capabilities for counter/timer alternate and special functions,

e.g. Counter/Timer out, load/store, enable/disable, etc. Refer also to the chapter on I/O

ports for further details.

Special Function Assignment

Port A:

Timer outputs in Pulse or Waveform modes can be tapped out of these pins: PA0 – PA3.

In order for the following timer outputs to drive their corresponding port pins, set the

respective bits in the Special Function Register of Port A to ones.

Table 25.
