the on-chip peripheral functions, PLL, and flash memory. However, because the PLL and flash memory are stopped,
a setup time for the PLL and flash memory is required when IDLE2 mode is released.
The IDLE2 mode is set by setting the PSMR.PSM1 and PSMR.PSM0 bits to 10 and setting the PSC.STP bit to 1 in
In the IDLE2 mode, the clock oscillator continues operation but clock supply to the CPU, PLL, flash memory, and
As a result, program execution stops and the contents of the internal RAM before the IDLE2 mode was set are
Table 23-7 shows the operating status in the IDLE2 mode.
The IDLE2 mode can reduce the power consumption more than the IDLE1 mode because it stops the operations of
Cautions 1. Insert five or more NOP instructions after the instruction that stores data in the PSC register
2. If the IDLE2 mode is set while an unmasked interrupt request signal is being held pending,
to set the IDLE2 mode.
the CPU does not shift to the IDLE2 mode but executes the next instruction.
