Function Documentation

◆ GPIO_DbgLocationSet()

void GPIO_DbgLocationSet ( unsigned int location )

Sets the pin location of the debug pins (Serial Wire interface).

Note: Changing the pins used for debugging uncontrolled, may result in a lockout.

Parameters

[in] location The debug pin location to use (0-3).

◆ GPIO_DriveModeSet()

void GPIO_DriveModeSet	(	GPIO_Port_TypeDef	`port,`
		GPIO_DriveMode_TypeDef	`mode`
	)

Sets drive mode for a GPIO port.

Parameters

[in]	`port`	The GPIO port to access.
[in]	`mode`	Drive mode to use for the port.

◆ GPIO_ExtIntConfig()

void GPIO_ExtIntConfig	(	GPIO_Port_TypeDef	`port,`
		unsigned int	`pin,`
		unsigned int	`intNo,`
		bool	`risingEdge,`
		bool	`fallingEdge,`
		bool	`enable`
	)

Configure the GPIO external pin interrupt.

It is recommended to disable interrupts before configuring the GPIO pin interrupt. See GPIO_IntDisable() for more information.

The GPIO interrupt handler must be in place before enabling the interrupt.

Notice that any pending interrupt for the selected interrupt is cleared by this function.

Note: On series 0 devices, the pin number parameter is not used. The pin number used on these devices is hardwired to the interrupt with the same number.
On series 1 devices, the pin number can be selected freely within a group. Interrupt numbers are divided into 4 groups (intNo / 4) and valid pin number within the interrupt groups are: 0: pins 0-3 (interrupt number 0-3) 1: pins 4-7 (interrupt number 4-7) 2: pins 8-11 (interrupt number 8-11) 3: pins 12-15 (interrupt number 12-15)

Parameters

[in]	`port`	The port to associate with the `pin`.
[in]	`pin`	The pin number on the port.
[in]	`intNo`	The interrupt number to trigger.
[in]	`risingEdge`	Set to true if the interrupt will be enabled on the rising edge. Otherwise, false.
[in]	`fallingEdge`	Set to true if the interrupt will be enabled on the falling edge. Otherwise, false.
[in]	`enable`	Set to true if the interrupt will be enabled after the configuration is complete. False to leave disabled. See GPIO_IntDisable() and GPIO_IntEnable().

◆ GPIO_PinModeSet()

void GPIO_PinModeSet	(	GPIO_Port_TypeDef	`port,`
		unsigned int	`pin,`
		GPIO_Mode_TypeDef	`mode,`
		unsigned int	`out`

Set the mode for a GPIO pin.

Parameters

[in]	`port`	The GPIO port to access.
[in]	`pin`	The pin number in the port.
[in]	`mode`	The desired pin mode.
[in]	`out`	A value to set for the pin in the DOUT register. The DOUT setting is important for some input mode configurations to determine the pull-up/down direction.

◆ GPIO_PinModeGet()

GPIO_Mode_TypeDef GPIO_PinModeGet	(	GPIO_Port_TypeDef	`port,`
		unsigned int	`pin`
	)

Get the mode for a GPIO pin.

void GPIO_EM4EnablePinWakeup	(	uint32_t	`pinmask,`
		uint32_t	`polaritymask`

When the function exits, EM4 mode can be safely entered.

Note: It is assumed that the GPIO pin modes are set correctly. Valid modes are gpioModeInput and gpioModeInputPull.

Parameters

[in]	`pinmask`	A bitmask containing the bitwise logic OR of which GPIO pin(s) to enable. See Reference Manuals for a pinmask to the GPIO port/pin mapping.
[in]	`polaritymask`	A bitmask containing the bitwise logic OR of GPIO pin(s) wake-up polarity. See Reference Manuals for pinmask-to-GPIO port/pin mapping.

◆ GPIO_DbgSWDClkEnable()

void GPIO_DbgSWDClkEnable ( bool enable )

inline

Enable/disable serial wire clock pin.

Note: Disabling SWDClk will disable the debug interface, which may result in a lockout if done early in startup (before debugger is able to halt core).

Parameters

[in]

enable

false - disable serial wire clock.
true - enable serial wire clock (default after reset).

◆ GPIO_DbgSWDIOEnable()

void GPIO_DbgSWDIOEnable ( bool enable )

inline

Enable/disable serial wire data I/O pin.

Note: Disabling SWDClk will disable the debug interface, which may result in a lockout if done early in startup (before debugger is able to halt core).

Parameters

[in]

enable

false - disable serial wire data pin.
true - enable serial wire data pin (default after reset).

◆ GPIO_EM4DisablePinWakeup()

void GPIO_EM4DisablePinWakeup ( uint32_t pinmask )

inline

Disable GPIO pin wake-up from EM4.

Parameters

[in] pinmask Bit mask containing the bitwise logic OR of which GPIO pin(s) to disable. Refer to Reference Manuals for pinmask to GPIO port/pin mapping.

uint32_t GPIO_EM4GetPinWakeupCause ( void )

inline

Check which GPIO pin(s) that caused a wake-up from EM4.

◆ GPIO_EM4SetPinRetention()

void GPIO_EM4SetPinRetention ( bool enable )

inline

Enable GPIO pin retention of output enable, output value, pull enable, and pull direction in EM4.

Note: On series 0 devices EM4 gpio retention can either be turned on or off. On series 1 devices there are three EM4 GPIO retention modes available. These modes are "Disabled", "EM4EXIT" and "SWUNLATCH". Use the EMU_EM4Init() to configure the GPIO retention mode on a series 1 device.

The behavior of this function depends on the configured GPIO retention mode. If the GPIO retention mode is configured to be "SWUNLATCH" then this function will not change anything. If the retention mode is anything else then this function will set the GPIO retention mode to "EM4EXIT" when the enable argument is true, and "Disabled" when false.

Parameters

[in]

enable

true - enable EM4 pin retention.
false - disable EM4 pin retention.

Note: A certain pin number can only be associated with one port; i.e., if GPIO interrupt 1 is assigned to port A/pin 1, then it is not possible to use pin 1 from any other ports for interrupts. Refer to the reference manual. On devices which implement GPIO_EXTIPINSEL registers a more flexible approach is possible, refer to GPIO_ExtIntConfig().
