IOKEEP Bit (I/O Port Retention)
In deep software standby mode, I/O ports keep retaining the same states from software standby mode. The IOKEEP bit
specifies whether to keep retaining the I/O port states from deep software standby mode even after deep software standby
mode is canceled, or to cancel retaining the I/O port states.
DPSBY Bit (Deep Software Standby)
The DPSBY bit controls transitions to deep software standby mode.
When the WAIT instruction is executed while the SSBY and DPSBY bits in SBYCR are 1, the LSI enters deep software
standby mode through software standby mode.
This bit is not cleared to 0 when deep software standby mode is canceled by the external interrupt pin. Write 0 to this bit
to clear.
When the WDT is used in watchdog timer mode, the setting of this bit is invalid. In this case, even when the SSBY and
DPSBY bits in SBYCR are set to 1, the LSI always enters sleep mode or all-module clock stop mode after the WAIT
instruction is executed.
