90 / 131 page ![]() Registers VMDS-10507 VSC8504-02 Datasheet Revision 4.2 79 4.6.4 GPIO Input The input register contains information about the input to the device GPIO pins. Read from this register to access the data on the device GPIO pins. The following table shows the readout you can expect. 4.6.5 GPIO Output The output register allows you to access and control the output from the device GPIO pins. The following table shows the values you can write.
