2.1.5 GPIO Interface
The following table shows the configuration variants for the GPIO pads. All variants are mutu-
ally exclusive, i.e. a pad configured for instance as Status LED is locked for alternative usage.
2.1.6 Digital Audio Interface
PLS63-W supports one digital audio interface that can be deployed as PCM. Inter_IC Sound
(I
2
S) interface is under development.
2.1.6.1 Pulse Code Modulation Interface
PLS63-W’s PCM interface can be used to connect audio devices capable of pulse code
modulation. The PCM functionality is limited to the use of wideband codec with 16kHz sample
rate only. The PCM interface runs at 16kHz sample rate (62.5μs frame length), while the
signal processing maintains this rate in a wideband AMR call or samples automatically down
