(a) Format and waveform example of normal transmit/receive data
Figures 14-15 and 14-16 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.
• Start bit ... 1 bit
• Character bits ... 7 or 8 bits
• 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 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).
Whether the T

D6 pin outputs normal or inverted data is specified by bit 0 (TXDLV6) of ASICL6.
