6.6 Data-Retention Mode
MC68HC705K1 — Rev. 2.0
In data-retention mode, the MCU retains random-access memory (RAM)
contents and CPU register contents at V
Data-retention mode 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 a logic 0.
2. Lower the V
1. Return V
2. Return the RESET pin to a logic 1.
