LC87F5LP6A
„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).
• The minimum instruction cycle selectable from 250ns, 500ns, 1.0µs, 2.0µs, 4.0µs, 8.0µs, 16.0µs, 32.0µs, and
64.0µs (at a main clock rate of 12MHz).
„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 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 lower 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 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
„On-chip Debugger Function
• Permits software debugging with the test device installed on the target board.
