19.2.1
SBYCR is an 8-bit readable/writable register that performs software standby mode control.
SBYCR is initialized to H'08 by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 7—Software Standby (SSBY): Specifies a transition to software standby mode. Remains set
to 1 when software standby mode is released by an external interrupt, and a transition is made to
normal operation. The SSBY bit should be cleared by writing 0 to it.

Bits 6 to 4—Standby Timer Select 2 to 0 (STS2 to STS0): These bits select the time the MCU
waits for the clock to stabilize when software standby mode is cleared by an external interrupt.
With crystal oscillation, refer to table 19.4 and make a selection according to the operating
frequency so that the standby time is at least 8 ms (the oscillation stabilization time). With an
external clock, any selection can be made * .
Note: * Except in the F-ZTAT versions.
