Technical Data
The STOP instruction:
The WAIT instruction:
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 the V
1. Return V
2. Return the RESET pin to logic 1.
The STOP instruction during erasable, programmable read-only
memory (EPROM) programming clears the EPGM bit in the EPROM
programming register, removing the programming voltage from the
EPROM.
The WAIT instruction has no effect on EPROM/one-time
programmable read-only memory (OTPROM) operation.
