LC87F7J32A

No.A0886-5/29

Standby Function

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

(Some parts of the serial transfer function stops operation)

1) Oscillation is not halted automatically.

2) Canceled by a system reset or 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 three ways of resetting the HOLD mode.

(1) Setting the reset pin to the low level

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

(3) 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

and the remote control circuit.

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 five ways of resetting the X'tal HOLD mode.

(1) Setting the reset pin to the low level

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

(3) Having an interrupt source established at port 0

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

(5) Having an interrupt source established in the infrared remote control receiver circuit

Same Package and Pin Assignment as Mask ROM Version.

1) LC877J00 series options can be set by using flash ROM data. Thus the board used for mass production can

be used for debugging and evaluation without modifications.

2) If the program for the mask ROM version is used, the usable ROM/RAM capacity is the same as

the mask ROM version.
