1. Change the value of the PSTOP1 bit from 0 to 1 to fix the Bφ output at the high level (given
2. Clear the IOKEEP bit to 0 to end retention of the Bφ state.
3. Clear the PSTOP1 bit to 0 to enable Bφ output.
For the port state when the IOKEEP bit is set to 1, see section 24.8.3, Pin State on Exit from Deep
Software Standby Mode.
24.8.5
The WTSTS5 to WTSTS0 bits in DPSWCR should be set as follows:
1. Using a crystal resonator
2. Using an external clock
that the Bφ output was already fixed high).
Specify the WTSTS5 to WTSTS0 bits so that the standby time is at least equal to the
oscillation settling time. Table 24.3 shows EXTAL input clock frequencies and the standby
time according to WTSTS5 to WTSTS0 settings.
The PLL circuit settling time should be considered. See table 24.3 to set the standby time.
(1) B φ output cannot be guaranteed.
(2) The procedure to guarantee B φ output is used.

When IOKEEP = 1, the clock can be normally output
by using the PSTOP1 bit.
