17.6.4 UART reception

beforehand.
of data input to RXDC0 is started. If the data is low level half a bit after detection of the falling edge (indicated by
Figure 17-9), it is recognized as a start bit. When the start bit has been recognized, reception is started, and serial
data is sequentially stored in the receive shift register at the specified baud rate. When the stop bit has been received,
the reception complete interrupt request signal (INTUC0R) is generated and, at the same time, the data stored in the
receive shift register is transferred to the receive data register (UC0RX).
On the other hand, even if a parity error (UC0PE = 1) or framing error (UC0FE = 1) occurs, reception continues and
the receive data is transferred to the UC0RX register. No matter which reception error has occurred, the INTUC0R
interrupt is generated after reception is complete.
First, enable reception by executing the following operations and monitor the RXDC0 input to detect the start bit.
• Specify the operating clock by using UARTC control register 1 (UC0CTL1).
• Specify the baud rate by using UARTC control register 2 (UC0CTL2).
• Specify the output logic level by using UARTC option control register 0 (UC0OPT0).
• Specify the communication direction, parity, data character length, and stop bit length by using UARTC control
• Set the power bit and reception enable bit (UC0PWR = 1 and UC0RXE = 1).
To change the communication direction, parity, data character length, and/or stop bit length, clear the power bit
The level input to the RXDC0 pin is sampled by using the operating clock. If the falling edge is detected, sampling
If an overrun error occurs (UC0OVE = 1), however, the receive data is not transferred to UC0RX, but is discarded.
