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.
