7. PCM IF
PCM_OUT, PCM_IN, PCM_CLK, PCM_SYNC carry one of bi-directional channel of voice
data using 13bits PCM at 8ks/s.
PCM_SYNC operates at a fixed clock frequency of 8kHz.
PCM_CLK operates at a fixed clock frequency of 256kHz.
Bits 1 to 13 of the PCM_OUT data carry the current output sample value.
Bits 14 to 16 carry a three bit signal level value.
Reference PCM audio device is MC145483.
8. PIO PORT
The PIO port is general purpose IO interface and the ports consists of 8 programmable,
Bi-directional PIO [2:8] . The maximum current drive capability is 4mA.
