Interrupt request output pin
When an interrupt request occurs, a “L” level is output. This pin
automatically outputs a “H” level after 32 Ts (T = 1/fosc).
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 (ceramic
resonator).
If external clock is used, input clock via XT pin. The XT pin should be left
open.
Receive input pin. Differential amplifier included.
