• UARTA receive data register n (UAnRX)
• UARTA transmit data register n (UAnTX)
• TXDAn: Output pin of transmit data
• RXDAn: Input pin of receive data
• Reception complete interrupt (INTUAnR): An interrupt is generated in the reception enabled
• Transmission enable interrupt (INTUAnT): Generated when transmit data is transferred from the
status by ORing three types of reception errors. It is also generated when receive data is
transferred from the shift register to receive buffer register n after completion of serial transfer.
transmit buffer register to the shift register in the transmission enabled status.
n = 0 to 1
