LC863232/28/24/20/16A - Interrupt priority control Three interrupt priorities are supported (low, high and highest) and multi-level nesting is possible. Low or high priority can be assigned to the interrupts from 3 to 10 listed above. For the external interrupt INT0 and INT1, high or highest priority can be set. (15) Sub-routine stack level - A maximum of 128 levels (stack is built in the internal RAM) (16) Multiplication/division instruction - 16 bits x 8 bits (7 instruction cycle times) - 16 bits / 8 bits (7 instruction cycle times) (17) 3 oscillation circuits - Built-in RC oscillation circuit used for the system clock - Built-in VCO circuit used for the system clock and OSD - X'tal oscillation circuit used for base timer, system clock and PLL reference (18) Standby function - 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. * Pull the reset terminal ( RES ) to low level. * Feed the selected level to either P70/INT0 or P71/INT1. * Input the interrupt condition to Port 0.

For further assistance, please contact with oscillator
Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation frequency on the production board. * The above oscillation frequency and the operating supply voltage range are based on the operating temperature of -10C to +70C. For the use with the temperature outside of the range herein, or in the applications requiring high reliability such as car products, please consult with oscillator manufacturer. * When using the oscillator which is not shown in the sample oscillation circuit characteristics, please consult with Sanyo sales personnel. Since the oscillation circuit characteristics are affected by the noise or wiring capacity because the circuit is designed with low gain in order to reduce the power dissipation, refer to the following notices. * The distance between the clock I/O terminal (XT1 terminal XT2 terminal) and external parts should be as short as possible. * The capacitors' VSS should be allocated close to the microcontroller's GND terminal and be away from other GND. * The signal lines with rapid state changes or with large current should be allocated away from the oscillation circuit.
