LC877264A/56A/48A
(16) Oscillation circuits
- On-chip RC oscillation for system clock use.
- CF oscillation for system clock use. (Rf built in, Rd external)
- Crystal oscillation low speed system clock use. (Rf built in, Rd external)
(17) Standby function
- HALT mode
HALT mode is used to reduce power consumption. During the HALT mode, program execution is stopped but
peripheral circuits keep operating (some parts of serial transfer operation stop.)
1) Oscillation circuits are not stopped automatically.
2) Released by the system reset or interrupts.
-HOLD mode
HOLD mode is used to reduce power consumption. Program execution and peripheral circuits are stopped.
1) CF, RC and crystal oscillation circuits stop automatically.
2) Released by any of the following conditions.
(1) Low level input to the reset pin
(2) Specified level input to one of INT0, INT1, INT2
(3) Port 0 interrupt
-X’tal HOLD made
X’tal HOLD mode is used to reduce power consumption. Program execution is stopped.
All peripheral circuits except the base timer are stopped.
1) CF and RC oscillation circuits stop automatically.
2) Crystal oscillator operation is kept in its state at HOLD mode inception.
3) Released by any of the following conditions
(1) Low level input to the reset pin
(2) Specified level input to one of INT0, INT1, INT2
(3) Port 0 interrupt
(4) Base-timer interrupt
