//---------------------------------------------------------------------------
// This function initializes GPIO pins to function as ECAP pins
//
// Each GPIO pin can be configured as a GPIO pin or up to 3 different
// peripheral functional pins. By default all pins come up as GPIO
// inputs after reset.
//
// Caution:
// For each eCAP peripheral
// Only one GPIO pin should be enabled for ECAP operation.
