(a) Format and waveform example of normal transmit/receive data
Figures 14-6 and 14-7 show the format and waveform example of the normal transmit/receive data.
One data frame consists of the following bits.
• Start bit ... 1 bit
• Character bits ... 7 or 8 bits (LSB first)
• Parity bit ... Even parity, odd parity, 0 parity, or no parity
• Stop bit ... 1 or 2 bits
The character bit length, parity, and stop bit length in one data frame are specified by asynchronous serial
interface operation mode register 0 (ASIM0).
