TECHNICAL DATA

9.1 Timer Structure
Figure 9-2 shows the capture/compare system block diagram. The port 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 lev-
el on PA[3:0] can be read at any time (read PORTA register), even if the pin is being
used for the input capture function. Pins PA[6:3] are used for either general-purpose
I/O, or as output compare pins. When one of these pins is being used for an output
compare function, it cannot be written directly as if it were a general-purpose output.
Each of the output compare functions (OC[5:2]) is related to one of the port A output
pins. Output compare one (OC1) has extra control logic, allowing it optional control of
any combination of the PA[7:3] pins. The PA7 pin can be used as a general-purpose
I/O pin, as an input to the pulse accumulator, or as an OC1 output pin.
