Timer overflow event
Mode
These events generate an interrupt if the corresponding enable control bit is set and the interrupt mask in
the CC register is reset (RIM instruction).
Interrupt event
No effect on 16-bit timer.
Timer interrupts cause the device to exit from wait mode.
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 MCU is woken up by an interrupt with ‘exit from halt mode’
capability or from the counter reset value when the MCU is woken up by a reset.
If an input capture event occurs on the ICAPi pin, the input capture detection circuitry is
armed. Consequently, when the MCU 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.
