Low-Power Modes
6.3.5.1 STOP
The STOP instruction during EPROM programming clears the EPGM bit in the EPROM programming
register, removing the programming voltage from the EPROM.
6.3.5.2 WAIT
The WAIT instruction has no effect on EPROM/OTPROM operation.
6.4 Data-Retention Mode
In data-retention mode, the MCU retains RAM contents and CPU register contents at V
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:
To take the MCU out of data-retention mode:
