#define ioport_set_pin_peripheral_mode	(		pin,
			mode
	)

Value:

do {\
		ioport_set_pin_mode(pin, mode);\
		ioport_disable_pin(pin);\
    } while (0)

Set peripheral mode for one single IOPORT pin.

It will configure port mode and disable pin mode (but enable peripheral).

Parameters

pin	IOPORT pin to configure
mode	Mode masks to configure for the specified pin (IOPORT Modes)
