22.7 Low-Power Modes
22.7.1 Wait Mode
22.7.2 Stop Mode
MC68HC908GR8 — Rev 4.0
MOTOROLA
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The TIM remains active after the execution of a WAIT instruction. In wait
mode, the TIM registers are not accessible by the CPU. Any enabled
CPU interrupt request from the TIM can bring the MCU out of wait mode.
If TIM functions are not required during wait mode, reduce power
consumption by stopping the TIM before executing the WAIT instruction.
The TIM is inactive after the execution of a STOP instruction. The STOP
instruction does not affect register conditions or the state of the TIM
counter. TIM operation resumes when the MCU exits stop mode after an
external interrupt.

For More Information On This Product,
TIM overflow flag (TOF) — The TOF bit is set when the TIM
counter value reaches the modulo value programmed in the TIM
counter modulo registers. The TIM overflow interrupt enable bit,
TOIE, enables TIM overflow CPU interrupt requests. TOF and
TOIE are in the TIM status and control register.
TIM channel flags (CH1F:CH0F) — The CHxF bit is set when an
input capture or output compare occurs on channel x. Channel x
TIM CPU interrupt requests and TIM DMA service requests are
controlled by the channel x interrupt enable bit, CHxIE. Channel x
TIM CPU interrupt requests are enabled when CHxIE = 1. CHxF
and CHxIE are in the TIM channel x status and control register.
DMAxS is in the TIM DMA select register.
