Microcontroller interface select pins.
Interrupt request output pin.
When an interrupt request occurs, a "L" level is output.
Three types of interrupts share this pin: transmission complete, reception complete,
and error.
Reset pin.
System is reset when this pin is at a "L" level.
Clock pins. If internal oscillator is used, connect a crystal oscillator. If external
clock is input, input clock via XT pin. The XT pin should be left open.
Receive input pin. Differential amplifier included.
Transmission output pin.
Internal logic power supply pin.
Internal logic GND pin.
Power supply pin for receive input differential amplifier.
GND pin for receive input differential amplifier.
