6.4.1 Programmable COP Watchdog in Wait Mode
6.4.2 Non-Programmable COP Watchdog in Wait Mode
6.5 Data-Retention Mode
MC68HC705C8A — Rev. 3
MOTOROLA
The programmable COP watchdog is active during wait mode. Software
must periodically bring the MCU out of wait mode to clear the
programmable COP watchdog.
The non-programmable COP watchdog is active during wait mode.
Software must periodically bring the MCU out of wait mode to clear the
non-programmable COP watchdog.
In data-retention mode, the MCU retains random-access memory (RAM)
contents and CPU register contents at V
The data-retention feature allows the MCU to remain in a low
power-consumption state during which it retains data, but the CPU
cannot execute instructions.
To put the MCU in data-retention mode:
To take the MCU out of data-retention mode:
1. Drive the RESET pin to logic 0.
2. Lower V
1. Return V
2. Return the RESET pin to logic 1.
