16-BIT TIMER (Cont’d)

11.4.4 Low Power Modes

Mode

WAIT

HALT

Description

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.

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 bits in the CC register are reset (RIM instruction).
