... The data transmit pin PCMT will go back to the high impedance state halfway through the LSB. The Short Frame Sync operation of the W681513 is based on an 8-bit data word. When receiving data on the PCMR pin, the data is clocked in on the first falling edge after the falling edge that coincides with the Frame Sync signal ...

... LOW for the entire frame sync period while the MCLK and BCLK pin clock signals are still present, the W681513 will enter the low power standby mode. Another way to power down is to set the PUI pin to low. When the system needs to be powered up again, the PUI pin needs to be set to HIGH and the Frame Sync pulse needs to be present ...
