#define ioc_input_sel	(	port,
		pin
	)	((port << 3) \| pin)

Generates an IOC_INPUT_SEL_PXn value from a port/pin number.

Parameters

port	The port as a number (PA: 0, PB: 1 etc)
pin	The pin as a number

Returns: A value which can be written in the INPUT_SEL bits of various IOC registers

Function Documentation

void ioc_set_over	(	uint8_t	port,
		uint8_t	pin,
		uint8_t	over
	)

Set Port:Pin override function.

Parameters

port	The port as a number (PA: 0, PB: 1 etc)
pin	The pin as a number
over	The desired override configuration

over can take the following values:

IOC_OVERRIDE_OE: Output
IOC_OVERRIDE_PUE: Pull-Up
IOC_OVERRIDE_PDE: Pull-Down
IOC_OVERRIDE_ANA: Analog
IOC_OVERRIDE_DIS: Disabled

void ioc_set_sel	(	uint8_t	port,
		uint8_t	pin,
		uint8_t	sel
	)

Function select for Port:Pin.

Parameters

port	The port as a number (PA: 0, PB: 1 etc)
pin	The pin as a number
sel	The desired function

The value of sel can be any of the IOC_PXX_SEL_xyz defines. For example IOC_PXX_SEL_UART0_TXD will set the port to act as UART0 TX
