LC87F6D64A
ÂSystem Clock Divider Function
⢠Able to reduce current consumption
Available minimum instruction cycle time: 300ns, 600ns, 1.2μs, 2.4μs, 4.8μs, 9.6μs, 19.2μs, 38.4μs, 76.8μs.
(Using 10MHz main clock)
ÂStandby Function
⢠HALT mode
HALT mode is used to reduce power consumption. Program execution is stopped. Peripheral circuits still operate
but VFD display and some serial transfer operations stop.
1) Oscillation circuits are not stopped automatically.
2) Release occurs on system reset or by interrupt.
⢠HOLD mode
HOLD mode is used to reduce power consumption. Both program execution and peripheral circuits are stopped.
1) The CF, RC, Xâtal and frequency variable RC oscillators automatically stop operation.
2) Release occurs on any of the following conditions.
(1) input to the reset pin goes âLowâ
(2) a specified level is input to at least one of INT0, INT1, INT2
(3) an interrupt condition arises at port 0
⢠Xâtal HOLD mode.
Xâtal HOLD mode is used to reduce power consumption. Program execution is stopped.
All peripheral circuits except the base-timer are stopped.
1) The CF, RC, frequency variable RC oscillation circuits stop automatically.
2) Crystal oscillator is maintained in its state at HOLD mode inception.
3) Release occurs on any of the following conditions.
(1) input to the reset pin goes âLowâ
(2) Setting at least one of the INT0, INT1 and INT2 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 remote control receiver circuit
ÂOn-chip Debugger
