23.6 STOP Mode/Low-Voltage STOP Mode
23.6.1 Setting and operation status
to 1 in the normal operation mode. The low-voltage STOP mode is set by setting the PSMR.PSM1 and PSMR.PSM0
bits to 01 or 11 and setting the PSC.STP bit to 1 after setting the REGOVL0 register to 01H in normal operation mode.

retained. Clock supply to the CPU and the on-chip peripheral functions is stopped, but the subclock oscillator
continues operating. In the STOP mode, CSIBn and UARTA0, which can operate on the external clock, also continue
operating. In the low-voltage STOP mode, however, stop supplying the external clock to CSIBn and UARTA0 (n = 0
to 4) because these blocks cannot continue operating.
voltage STOP mode.
lower than the IDLE2 mode. If the subclock oscillator, internal oscillator, low-voltage detector (LVI), and external clock
are not used, the power consumption can be minimized with only leakage current flowing.
lowered.
The STOP mode is set by setting the PSMR.PSM1 and PSMR.PSM0 bits to 01 or 11 and setting the PSC.STP bit
In the STOP mode, the subclock oscillator continues operating but the main clock oscillator stops. Clock supply to
As a result, program execution stops, and the contents of the internal RAM before the STOP mode was set are
Table 23-8 shows the operating status in the STOP mode and Table 23-9 shows the operating status in the low-
Because the STOP mode stops operation of the main clock oscillator, it reduces the power consumption to a level
The power consumption decreases further in the low-voltage STOP mode because the voltage of the regulator is
Be sure to set the low-voltage STOP mode using the following procedure.
