2.1.7 GPIO Interface
PLSx3 offers a GPIO interface with 22 GPIO lines. The GPIO lines are shared with other inter-
faces or functions: Fast shutdown (see Section 2.1.10.3), Status LED (see Section 2.1.10.1),
ASC0 (see Section 2.1.4), ASC1 (see Section 2.1.5) and SIM Switch (see Section 2.1.6.2)
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.
2.1.8 Digital Audio Interface
PLSx3 supports the digital audio interface that can be deployed as PCM or Inter_IC Sound
(I
2
S).
