takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.

Standby Function
•
HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.

(3) Occurrence of an interrupt

HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.
1) The CF, RC, X’tal, and frequency variable RC oscillators automatically stop operation.
2) There are four ways of resetting the HOLD mode.
(1) Setting the reset pin to the low level.
(2) System resetting by watchdog timer
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4, INT5, INT6, or INT7
* INT0 and INT1 HOLD mode reset is available only when level detection is set.
(4) Having an interrupt source established at port 0
•
X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.
1) The CF, RC, and frequency variable RC oscillators automatically stop operation.
2) The state of crystal oscillation established when the X'tal HOLD mode is entered is retained.
3) There are six ways of resetting the X'tal HOLD mode.
(1) Setting the reset pin to the low level
(2) System resetting by watchdog timer
(3) Having an interrupt source established at either INT0, INT1, INT2, INT4, INT5, INT6, or INT7
* INT0 and INT1 HOLD mode reset is available only when level detection is set.
(4) Having an interrupt source established at port 0
(5) Having an interrupt source established in the base timer circuit
(6) Having an interrupt source established in the day and time counter circuit
