P indicates power pins; I indicates pins for digital signal input; O indicates pins for digital
signal output.
The NC (Not Connected) pins are internally connected to the module. Therefore, these pins
should not be used, otherwise they may cause problems. Please contact us for more
details about this information.
When the MC509 module works on master mode, PCM_CLK and PCM_SYNC pins are in
the output status
Figure 3-1 shows the sequence of pins on the 145-pin signal interface of the MC509
module.
