16-BIT TIMER (Cont’d)
11.3.4 Low Power Modes
11.3.5 Interrupts
Note: The 16-bit Timer interrupt events are connected to the same interrupt vector (see Interrupts chap-
ter). 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).

MODES
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 ICAP i pin, the input capture detection circuitry is armed. Consequent-
ly, when the MCU is woken up by an interrupt with “exit from HALT mode” capability, the ICF i bit is set, and
the counter value present when exiting from HALT mode is captured into the IC i R register.
