6.2 Data Retention Mode
In data retention mode, the MCU retains RAM contents and CPU register contents
at VDD voltages as low as 2.0 Vdc. 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:
1. Drive the RESET pin to zero.
2. Lower the VDD voltage. The RESET line must remain low continuously
during data retention mode.
To take the MCU out of data retention mode:
1. Return VDD to normal operating voltage.
2. Return the RESET pin to logical one.
