... SD pin. The next three pulses on ACK pin will shift the remaining latched bits in a serial format (see Figure 5). If less than four pulses are applied to the ACK pin, new data cannot be latched even though ESt/DStD can be valid. Clock pulses should be applied to clock out any remaining data bits to resume normal operation. Any transitions in excess 4 Zarlink Semiconductor Inc. Data Sheet th ...
