GENERAL DESCRIPTION
These peripherals are supported by a twelve sources two-level interrupt capability. The W78C801 does not contain serial port. The W78C801 microcontroller has two power reduction modes, idle mode and power-down mode, both of which are software selectable. The idle mode turns off the processor clock but allows for continued peripheral operation. The power-down mode stops the crystal oscillator for minimum power consumption. The external clock can be stopped at any time and in any state without affecting the processor.FEATURES
