(a) Format and waveform example of normal transmit/receive data
Figures 14-14 and 14-15 show the format and waveform example of the normal transmit/receive data.
1. LSB-first transmission/reception
2. MSB-first transmission/reception
One data frame consists of the following bits.
The character bit length, parity, and stop bit length in one data frame are specified by asynchronous serial
interface operation mode register 6 (ASIM6).
Whether data is communicated with the LSB or MSB first is specified by bit 1 (DIR6) of asynchronous serial
interface control register 6 (ASICL6).

Start bit ... 1 bit
Character bits ... 7 or 8 bits
Parity bit ... Even parity, odd parity, 0 parity, or no parity
