Operating Modes
6.3.4 Data-Retention Mode
In the data-retention mode, the MCU retains random-access memory (RAM) contents and CPU register
contents at V
low-power consumption state during which it retains data, but the CPU cannot execute instructions.
Current consumption in this mode is not tested.
To put the MCU in the data retention mode:
To take the MCU out of the 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.
