Power-down modes are controlled by the following registers. To access SBYCR, LPWRCR,
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).

Description
Software Standby
Specifies the operating mode to be entered after executing
the SLEEP instruction.
When the SLEEP instruction is executed in high-speed
mode or medium-speed mode:
0: Shifts to sleep mode
1: Shifts to software standby mode, subactive mode, or
When the SLEEP instruction is executed in subactive
mode:
0: Shifts to subsleep mode
1: Shifts to watch mode or high-speed mode
Note that the SSBY bit is not changed even if a mode
transition occurs by an interrupt.
