21.2
21.2.1
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 21-4 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: * Not available in the F-ZTAT version.
