13.5 Operation
(1) Data format
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 stop bits as shown in Figure 13-3.
The character bit length within one data frame, the type of parity, and the stop bit length are specified by
asynchronous serial interface mode register n (ASIMn).
Also, data is transferred LSB 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
