13.1.2 Registers
13.2 Dependencies
13.2.1 I/O Pins
The output of Timer A does not come out directly on any of the I/O pins. It can be used to
control when the output occurs on Parallel Ports D–E, and can affect the output times of
Serial Ports A–F and the PWM.
13.2.2 Clocks
The timers in Timer A can be clocked by either perclk or perclk/2, as selected in TAPR. In
addition, timers A2–A7 can be clocked by the output of timer A1 by selecting that option
in TACSR.
