that can operate with the subclock or an external clock continue operating.
the on-chip peripheral functions. The main clock oscillator does not stop, so the normal operation mode can be
restored without waiting for the oscillation stabilization time after the IDLE1 mode has been released, in the same
manner as when the HALT mode is released.

The IDLE1 mode is set by clearing the PSMR.PSM1 and PSMR.PSM0 bits to 00 and setting the PSC.STP bit to 1
In the IDLE1 mode, the clock oscillator, PLL, and flash memory continue operating but clock supply to the CPU and
As a result, program execution stops and the contents of the internal RAM before the IDLE1 mode was set are
Table 23-5 shows the operating status in the IDLE1 mode.
The IDLE1 mode can reduce the power consumption more than the HALT mode because it stops the operation of
Cautions 1. Insert five or more NOP instructions after the instruction that stores data in the PSC register

the CPU does not shift to the IDLE1 mode but executes the next instruction.
