LC87F1JJ4B

No.A1537-5/28

Standby Function

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

1) Oscillation is not halted automatically.

2) There are three ways of releasing the HALT mode.

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

(2) System resetting by watchdog timer

(3) Generating an interrupt

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

1) The PLL base clock generator, CF, RC and crystal oscillators automatically stop operation.

2) There are five ways of releasing the HOLD mode.

(1) Setting the reset pin to the lower level

(2) System resetting by watchdog timer

(3) Having an interrupt source established at one of the INT0, INT1, INT2, INT4, and INT5 pins

* The INT0 and INT1 pins must be configured only for level detection.

(4) Having an interrupt source established at port 0

(5) Having an bus active interrupt source established in the USB host control circuit

• X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer.

1) The PLL base clock generator, CF and RC oscillator automatically stop operation.

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

3) There are seven ways of releasing 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 one of the INT0, INT1, INT2, INT4, and INT5 pins

* The INT0 and INT1 pins must be configured only for level detection.

(4) Having an interrupt source established at port 0

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

(6) Having an bus active interrupt source established in the USB host control circuit

(7) Having an interrupt source established in the infrared remote controller receiver circuit

Note 1: PC-less standalone onboard programming is possible using the FSG onboard programmer (AF9101/AF9103)

and the serial interface driver (SIB87) provided by SANYO in pair.

Note 2: Dedicated programming device and program are required depending on the programming conditions. Contact

SANYO or FSG if you have any questions or difficulties regarding this matter.
