static void _system_pinmux_config ( PortGroup *const  port, const uint32_t  pin_mask, const struct system_pinmux_config *const  config  )

static

Writes out a given configuration of a Port pin configuration to the hardware module.

Note

If the pin direction is set as an output, the pull-up/pull-down input configuration setting is ignored.

Parameters

[in]	port	Base of the PORT module to configure
[in]	pin_mask	Mask of the port pin to configure
[in]	config	Configuration settings for the pin
