LC875J96B/875J80B/875J72B
„Oscillation Circuits
• RC oscillation circuit (internal):
For system clock
• CF oscillation circuit:
For system clock, with internal Rf
• Crystal oscillation circuit:
For low-speed system clock, with internal Rf
• Frequency variable RC oscillation circuit (internal): For system clock
„System Clock Divider Function
• Can run on low current.
• The minimum instruction cycle selectable from 300ns, 600ns, 1.2µs, 2.4µs, 4.8µs, 9.6µs, 19.2µs, 38.4µs,
and 76.8µs (at a main clock rate of 10MHz).
„Standby Function
• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue 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, and crystal 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.
1) The CF and 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 four 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
