According to Figure 5-1, a character consists of ten consecutive moments numbered 1 to 10. Each moment is either at state H or at state L. Before moment 1, the electrical circuit I/O shall be at state H. Moment 1 shall be at state L. It is the character start. Moments 2 to 9 shall encode a byte according to a coding convention(send the LSB first). Moment 10 shall encode the character parity. After moment 10, both the card and the interface device shall remain in reception mode (in error-free operation) for a certain time of pause, so that the electrical circuit I/O remains at state H. 5.2 TimeCOS_PBOC Protocol Figure 5-1: Character Format Data Figure 5-2: Command and Response Frame Format MCU-AN E-10 Page 8
