Section 3 MCU Operating Modes
3.3
SYSCR is an 8-bit register that controls the operation of the H8/3067 Group.
Bit 7—Software Standby (SSBY): Enables transition to software standby mode. (For further
information about software standby mode see section 20, Power-Down State.)
When software standby mode is exited by an external interrupt, this bit remains set to 1. To clear
this bit, write 0.
