The power supply for the analog and digital parts of the W6810 must be 5V +/- 10%. This supply
voltage is connected to the V
ceramic capacitor.
The system has an internal precision voltage reference which generates the 2.5V mid-supply analog
ground voltage. This voltage needs to be decoupled to V
capacitor.
The analog ground reference voltage is available for external reference at the V
needs to be decoupled to V
voltage is generated from the voltage on the V
processing.
The PCM interface is controlled by pins BCLKR, FSR, BCLKT & FST. The input data is received
through the PCMR pin and the output data is transmitted through the PCMT pin. The modes of
operation of the interface are shown in Table 7.3.
