HALT mode
The HALT mode is used to reduce the power dissipation. In this operation mode, the program execution is stopped.
This mode can be released by the interrupt request or the system reset.
•
HOLD mode
The HOLD mode is used to stop the oscillations ; RC (internal), VCO, and X’tal oscillations.
This mode can be released by the following conditions.
1. Pull the reset terminal (RES) to low level.
2. Feed the selected level to either P70/INT0 or P71/INT1.
