2.2.2
The WAIT instruction places the MCU in a low power consumption mode, but WAIT mode
consumes more power than STOP mode. All CPU action is suspended and the watchdog is
disabled, but the timer, A/D and SCI and MCAN systems remain active and operate as normal (see
flow chart in
input/output lines remain unchanged. The programming or erase mechanism of the EEPROM is
also unaffected, as well as the charge pump high voltage generator.
During WAIT mode the I-bit in the CCR is cleared to enable all interrupts. The INTE bit in the
miscellaneous register
is sensed, the program counter vectors to the locations containing the start address of the interrupt
or reset service routine.
Any interrupt or reset condition causes the processor to exit WAIT mode.
If an interrupt exit from WAIT mode is performed, the state of the remaining systems will be
unchanged.
If a reset exit from WAIT mode is performed the entire system reverts to the disabled reset state.
Note:
MC68HC05X16
The stacking corresponding to an eventual interrupt to leave WAIT mode will only be
executed when leaving WAIT mode.
