LC87F57C8A
(18) Standby function
- HALT mode
The HALT mode stops program execution while the peripheral circuits keep operating and
minimizes power consumption. This operation mode can be released by a system reset or an
interrupt request.
- HOLD mode
The HOLD mode stops program execution and all oscillation circuits: CF, RC and Crystal
oscillations. This mode can be released by the following conditions.
1. Supply "L" level to the reset terminal (RES)
2. Supply the selected level to at lease one of INT0, INT1, INT2, INT4 INT5.
3. Supply an interrupt condition to Port 0.
- X’tal HOLD mode
The X’tal HOLD mode stops program execution and all peripheral circuits except for the base timer.
The crystal oscillator maintains its state at HOLD mode inception. This mode can be released by
the following conditions.
1. Supply "L" level to the reset terminal (RES).
2. Supply the selected level to at least one of INT0, INT1, INT2, INT4, INT5
3. Supply an interrupt condition to Port 0.
4. Supply an interrupt condition to the base timer circuit.
