8.3 Timer structure
MC68HC11P2 — Rev 1.0
The timer functions share I/O with all eight pins of port A:
Figure 8-2
A pin control block includes logic for timer functions and for general-
purpose I/O. For pins PA3, PA2, PA1 and PA0, this block contains both
the edge-detection logic and the control logic that enables the selection
of which edge triggers an input capture. The digital level on PA[3:0] can
be read at any time (read PORTA register), even if the pin is being used
