The WAIT and STOP instructions can put the MCU in low power consumption standby modes which will provide more benefit for Motorola MC68HC08AS20 MCU Flash Copying.
The WAIT instruction does not affect the EEPROM. It is possible to start the program or erase sequence on the EEPROM and put the MCU in wait mode.
The STOP instruction reduces the EEPROM power consumption to a minimum. The STOP instruction should not be executed while the programming and erasing sequence is in progress of Unlock MC68HC705C8A MCU Flash Memory.
If stop mode is entered while EELAT and EEPGM is set, the programming sequence will be stopped and the programming voltage to the EEPROM array removed. The programming sequence will be restarted after leaving stop mode; access to the EEPROM is only possible after the programming sequence has completed.
If stop mode is entered while EELAT and EEPGM is cleared, the programming sequence will be terminated abruptly.
In either case, the data integrity of the EEPROM is not guaranteed when Recover MCU.
Four I/O registers and three non-volatile registers control program, erase, and options of the EEPROM array.
This read/write register controls programming/erasing of the EEPROM array.
