Particular function select register 1
STP-instruction-execution status bit
(Note 1)
0: Normal operation.
1: STP instruction has been executed.
WIT-instruction-execution status bit
(Note 1)
0: Normal operation.
1: WIT instruction has been executed.
Standby state select bit
0: External bus
1: Programmable I/O port
System clock stop select bit at WIT
(Note 2)
0: In wait mode, system clock f
sys
is active.
1: In wait mode, system clock f
sys
is stopped.
Address output select bit
0: Address changes depending on bus access.
1: Address changes only at access to external address.
Timer B2 clock source select bit
In event counter mode:
0: Clock input from pin TB2
IN
is counted.
1: fX
32
(f(X
IN
)/32) is counted.

Notes 1:
At power-on reset, this bit becomes
“
0
”
. At hardware reset or software reset, this bit
retains the value just before reset. Even when
“
1
”
is written, the bit status will not change.
2:
Setting this bit to
“
1
”
must be performed just before execution of the WIT instruction.
Also, after the wait state is terminated, this bit must be cleared to
“
0
”
immediately.

, after the os-
cillation circuit and PLL circuit have been restarted their operations
owing to an interrupt. The most significant bit of the watchdog timer
reaching
“
0
”
, supply of
φ
BIU
and
φ
CPU
restarts.
On the other hand, when the external clock input select bit =
“
1
”
and
the system clock select bit =
“
0
”
, supply of
φ
BIU
and
φ
CPU
will restart
immediately after the oscillation circuit has been restarted their op-
erations owing to an interrupt. (In actual fact, after the selected one
of the above divide clocks, fX
16
to fX
128
, has been changed from
“
H
”
to
“
L
”
, this supply will restart.)
