16-BIT TIMER

10.3.4 Low Power Modes

10.3.5 Interrupts

Note:

10.3.6 Summary of Timer modes

3) See note 4 in Section 10.3.3.6 Pulse Width Modulation Mode

Wait

No effect on 16-bit Timer.

Timer interrupts cause the Device to exit from Wait mode.

Halt

16-bit Timer registers are frozen.

In Halt mode, the counter stops counting until Halt mode is exited. Counting resumes from the previous count

when the Device is woken up by an interrupt with “exit from Halt mode” capability or from the counter reset

value when the Device is woken up by a RESET.

If an input capture event occurs on the ICAPi pin, the input capture detection circuitry is armed. Consequent-

ly, when the Device is woken up by an interrupt with “exit from Halt mode” capability, the ICFi bit is set, and

the counter value present when exiting from Halt mode is captured into the ICiR register.
