The UCnCTL0 register is an 8-bit register used to specify the UARTCn operation.
The UCnCTL1 register is an 8-bit register used to select the input clock for the UARTCn.
The UCnCTL2 register is an 8-bit register used to control the baud rate for the UARTCn.
The UCnOPT0 register is an 8-bit register used to control serial transfer for the UARTCn.
The UCnOPT1 register is an 8-bit register used to control 9-bit length serial transfer for the UARTCn.
The UCnSTRn register consists of flags indicating the error contents when a reception error occurs. Each one
of the reception error flags is set (to 1) upon occurrence of a reception error.
This is a shift register used to convert the serial data input to the RXDCn pin into parallel data. Upon reception
of 1 byte of data and detection of the stop bit, the receive data is transferred to the UCnRX register.
This register cannot be manipulated directly.
The UCnRX register is an 8-bit register that holds receive data. When 7 characters are received, 0 is stored in
the most significant bit (when data is received with the LSB first).
In the reception enabled status, receive data is transferred from the UARTCn receive shift register to the
UCnRX register in synchronization with the completion of shift-in processing of 1 frame.
Transfer to the UCnRX register also causes the reception completion interrupt request signal (INTUCnR) to be
output.
The transmit shift register is a shift register used to convert the parallel data transferred from the UCnTX
register into serial data.
When 1 byte of data is transferred from the UCnTX register, the shift register data is output from the TXDCn
pin.
This register cannot be manipulated directly.
The UCnTX register is an 8-bit transmit data buffer. Transmission starts when transmit data is written to the
UCnTX register. When data can be written to the UCnTX register (when data of one frame is transferred from
the UCnTX register to the UARTCn transmit shift register), the transmission enable interrupt request signal
(INTUCnT) is generated.
