15.7 Operation
15.7.1 Data format
stop bits as shown in Figure 15-3.
control register 0 (UBCTL0).
Full-duplex serial data transmission and reception can be performed.
The transmit/receive data format consists of one data frame containing a start bit, character bits, a parity bit, and
The character bit length within one data frame, the type of parity, and the stop bit length are specified by UARTB
Also, data is transferred with LSB first/MSB first.
• Start bit ··· 1 bit
• Character bits ··· 7 bits or 8 bits
• Parity bit ··· Even parity, odd parity, 0 parity, or no parity
• Stop bits ··· 1 bit or 2 bits
