A/D CONVERTER
The
µPD78324 incorporates a high-speed, high-resolution 10-bit analog/digital (A/D) converter. This A/D converter is
equipped with eight analog inputs (AN0 to AN7) and A/D conversion result register (ADCR) which holds the conversion
results. Upon termination of conversion, the interrupt which can start the macro service is generated.

SERIAL INTERFACE
The
µPD78324 is equipped with the following two independent channels for the serial interface function.
Asynchronous serial interface
Clock synchronous serial interface
•
3-wire serial I/O mode
•
Serial bus interface mode (SBI mode)
Since the
µPD78324 incorporates a baud rate generator, it can set any serial transfer rate irrespective of the operating
frequency. The baud rate generator functions for the 2-channel serial interface.
The serial transfer rate can be selected from 75 bps to 19.2 Kbps by setting the mode register.
