For operating modes after the reset state is cancelled, this LSI has four power-down operating
modes in which power consumption is significantly reduced. In addition, there is also module stop
mode in which reduced power consumption can be achieved by individually stopping on-chip
peripheral modules.
• Medium-speed mode
• Sleep mode
• Watch mode
• Software standby mode
• Module stop mode
26.1
Power-down modes are controlled by the following registers. To access SBYCR, LPWRCR,
SYSCR2, MSTPCRH, and MSTPCRL the FLSHE bit in the serial timer control register (STCR)
must be cleared to 0. For details on STCR, see section 3.2.3, Serial Timer Control Register
(STCR). For details on the PSS bit in TSCR_1 (WDT_1), see TCSR_1 in section 13.3.5, Timer
Control/Status Register (TCSR).

System clock frequency for the CPU operation can be selected as φ/2, φ/4, φ/8, φ/16 or φ/32.
The CPU stops but on-chip peripheral modules continue operating.
The CPU stops, but on-chip peripheral module WDT_1 and CIR continue operating.
The clock pulse generator stops, and the CPU and on-chip peripheral modules stop operating.
Independently of above operating modes, on-chip peripheral modules that are not used can be
stopped individually.
