reception<br />

: Indicates that waveform error is detected. The error occurs when waveform error<br />

detection is enabled in CECRCR3 .<br />

: Indicates the receive buffer receives next data before reading the data that had<br />

already been set.<br />

: Indicates “0” is detected after the specified time to output ACK bit “0”.<br />

: Indicates one bit cycle is shorter than the minimum cycle error detection time<br />

specified in CECRCR1.<br />

: Indicates one bit cycle is longer than the maximum cycle error detection time<br />

specified in CECRCR1.<br />

: Indicates a start bit is detected.<br />

: Indicates 1 byte of data reception is completed.<br />

(Note) Writing to this bit is ignored.<br />
