Slave mode
In slave mode, PCM_CLK and PCM_FSC is input port.
PCM_FSC
8K short sync or long sync.
PCM_CLK
PCM_IN
768 KHz ~ 2048 KHz
When sync is coming, it starts to catch MSB in (first sync rising + delay1 bits). LSB is depending 8bits or
16bits for first slot. Data rate is 1x or 1/2 Clk.
PCM_OUT
When sync is coming, it starts to send MSB in (first sync rising + delay1 bits). LSB is depending 8bits or
16bits for first slot. Data rate is 1x or 1/2 Clk.
