7.7.1 Wait Mode
MC68HC708MP16
Freescale Semiconductor
Rev. 3.1
In wait mode, the CPU clocks are inactive while the peripheral clocks
continue to run.
A module that is active during wait mode can wake up the CPU with an
interrupt if the interrupt is enabled. Stacking for the interrupt begins one
cycle after the WAIT instruction during which the interrupt occurred.
Refer to the wait mode subsection of each module to see if the module
is active or inactive in wait mode. Some modules can be programmed to
be active in wait mode.
Wait mode can also be exited by a reset or break. A break interrupt
during wait mode sets the SIM break stop/wait bit, SBSW, in the SIM
break status register (SBSR). If the COP disable bit, COPD, in the
configuration register is logic 0, then the computer operating properly
module (COP) is enabled and remains active in wait mode.
