Function Documentation

R_BSP_PinRead()

__STATIC_INLINE uint32_t R_BSP_PinRead

(

bsp_io_port_pin_t

pin

)

Read the current input level of the pin.

Parameters

[in]

pin

The pin

Return values

Current

input level

R_BSP_PinWrite()

__STATIC_INLINE void R_BSP_PinWrite	(	bsp_io_port_pin_t	pin,
		bsp_io_level_t	level
	)

Set a pin to output and set the output level to the level provided. If PFS protection is enabled, disable PFS protection using R_BSP_PinAccessEnable() before calling this function.

Parameters

[in]	pin	The pin
[in]	level	The level

R_BSP_PinCfg()

__STATIC_INLINE void R_BSP_PinCfg	(	bsp_io_port_pin_t	pin,
		uint32_t	cfg
	)

Configure a pin. If PFS protection is enabled, disable PFS protection using R_BSP_PinAccessEnable() before calling this function.

Parameters

[in]	pin	The pin
[in]	cfg	Configuration for the pin (PmnPFS register setting)

R_BSP_PinAccessEnable()

__STATIC_INLINE void R_BSP_PinAccessEnable

(

void

)

Enable access to the PFS registers. Uses a reference counter to protect against interrupts that could occur via multiple threads or an ISR re-entering this code.

R_BSP_PinAccessDisable()

__STATIC_INLINE void R_BSP_PinAccessDisable

(

void

)

Disable access to the PFS registers. Uses a reference counter to protect against interrupts that could occur via multiple threads or an ISR re-entering this code.
