LC878496PB/C8PB/G0PB/G1PB/J2PB/J3PB/M4PB/P6PB/P7PB

No.A1795-5/29

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

1) Oscillation is not halted automatically.

2) Canceled by system reset, detection VDET0 or occurrence of interrupt.

• HOLD mode: Suspends instruction execution and the operation of the peripheral circuits.

1) The CF oscillators, RC, and crystal oscillators automatically stop operation.

2) There are four ways of resetting the HOLD mode.

(1) Setting the Reset pin to the lower level.

(2) Voltage descent detection (VDET1)

(3) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level.

(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 oscillators, and RC oscillators automatically stop operation.

2) The state of crystal oscillation established when X’tal HOLD mode is entered is retained.

3) There are five ways of resetting the X'tal HOLD mode.

(1) Setting the Reset pin to the low level.

(2) Voltage descent detection (VDET0)

(3) Setting at least one of the INT0, INT1, INT2, INT4, and INT5 pins to the specified level.

(4) Having an interrupt source established at port 0.

(5) Having an interrupt source established in the base timer circuit.
