The GPIO mux registers must be configured to connect this peripheral to the device pins. To avoid glitches on the pins, the GPyGMUX bits must be configured first (while keeping the corresponding GPyMUX bits at the default of zero), followed by writing the GPyMUX register to the desired value.
For proper operation of the eQEP module, input GPIO pins must be configured using the GPxQSELn registers for synchronous input mode (with or without qualification). The asynchronous mode cannot be used for eQEP input pins. The internal pullups can be configured in the GPyPUD register.
See the General-Purpose Input/Output (GPIO) chapter for more details on GPIO mux and settings.
