23B.1.1 Register Configuration
Power-down modes are controlled by the SBYCR, SCKCR, LPWRCR, TCSR (WDT1), and
MSTPCR registers. Table 23B-4 summarizes these registers.

23B.2 Register Descriptions
23B.2.1 Standby Control Register (SBYCR)
SBYCR is an 8-bit readable/writable register that performs power-down mode control.
SBYCR is initialized to H'58 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 7—Software Standby (SSBY): When making a low power dissipation mode transition by
executing the SLEEP instruction, the operating mode is determined in combination with other
control bits.
Note that the value of the SSBY bit does not change even when shifting between modes using
interrupts.
