Notes 1:
When not using the PLL frequency multiplier, clear this bit to
“

the flash memory parallel I/O mode, the PLL circuit stops it

is invalid.
2:
When rewriting this bit, be sure to clear bit 5 to
“
0
”
simultaneously. Also, after this bit is
rewritten, insert a waiting time of 2 ms, and then set bit 5 to
“
1
”
.
3:
When the PLL circuit operation enable bit (bit 1) has been cleared to
“
0

, this bit will also
be cleared to

(Note)
0: Oscillation circuit is active. (Oscillator is connected.)
Watchdog timer is used at stop mode termination.
1: Oscillation circuit is inactive. (External clock is input.)
When the system clock select bit =
“

,
watchdog timer is not used at stop mode termination.
When the system clock select bit =
“

,
watchdog timer is used at stop mode termination.
Fix this bit to

STP instruction invalidity select bit
(Note)
0: STP instruction is valid.
1: STP instruction is invalid.

Writing to these bits requires the following procedure:
Write
“

”
to this register. (The bit status does not change only by this writing.)
Succeedingly, write
“
0
”
or
“
1
”
to each bit.
Also, use the MOVM (MOVMB) instruction or STA (STAB, STAD) instruction
