#define PPF   (*_ppf[19])

#define PPF_CLR   (*_ppf[17])

#define PPF_DIR   (*_ppf[3])

For all bits, 0 - Input, 1 - Output

#define PPF_EDG   (*_ppf[6])

For all bits, 0 - Level, 1 - Edge

#define PPF_FER   (*_ppf[2])

For all bits, 0 - GPIO mode, 1 - Enable peripheral function

#define PPF_HST   (*_ppf[0])

These registers configure hysteresis for the PORTx inputs. For each controlled group of pins, b#0 will disable Schmitt triggering (hysteresis), while b#1 will enable it.

#define PPF_INE   (*_ppf[4])

For all bits, 0 - Input Buffer Disabled, 1 - Input Buffer Enabled

#define PPF_MCA   (*_ppf[12])

For all bits, 1 - Clear

#define PPF_MCB   *_ppf[13]

For all bits, 1 - Clear

#define PPF_MKA   (*_ppf[8])

For all bits, 1 - Enable, 0 - Disable

#define PPF_MKB   (*_ppf[9])

For all bits, 1 - Enable, 0 - Disable

#define PPF_MSA   (*_ppf[10])

For all bits, 1 - Set

#define PPF_MSB   (*_ppf[11])

For all bits, 1 - Set

#define PPF_MTA   (*_ppf[14])

For all bits, 1 - Toggle

#define PPF_MTB   (*_ppf[15])

For all bits, 1 - Toggle

#define PPF_MUX   (*_ppf[1])

For all bit fields: 0 = Peripheral function, 1 = Alternate peripheral function

#define PPF_POL   (*_ppf[5])

For all bits, 0 - Active high or rising edge, 1 - Active low or falling edge

#define PPF_RSE   (*_ppf[7])

For all bits when enabled for edge-sensitivity, 0 - Single edge, 1 - Both edges

#define PPF_SET   (*_ppf[16])

#define PPF_TGL   (*_ppf[18])
