Note
It is assumed that the GPIO pin modes are set correctly. Valid modes are gpioModeInput and gpioModeInputPull.
Parameters
[in]pinmaskA 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.

__STATIC_INLINE uint32_t GPIO_EM4GetPinWakeupCause ( void  )

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

Returns
Bit mask containing the bitwise logic OR of which GPIO pin(s) caused the wake-up. Refer to Reference Manuals for pinmask to GPIO port/pin mapping.

References _GPIO_EM4WUCAUSE_MASK, and GPIO.

__STATIC_INLINE void GPIO_EM4SetPinRetention ( bool  enable)

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.

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]portThe port to associate with the pin.
[in]pinThe pin number on the port.
[in]intNoThe interrupt number to trigger.
[in]risingEdgeSet to true if the interrupt will be enabled on the rising edge. Otherwise, false.
[in]fallingEdgeSet to true if the interrupt will be enabled on the falling edge. Otherwise, false.
[in]enableSet to true if the interrupt will be enabled after the configuration is complete. False to leave disabled. See GPIO_IntDisable() and GPIO_IntEnable().

__STATIC_INLINE void GPIO_InputSenseSet ( uint32_t  val,
uint32_t  mask 
)

Enable/disable input sensing.

Disabling input sensing if not used, can save some energy consumption.

Parameters
[in]valBitwise logic OR of one or more of:
  • GPIO_INSENSE_INT - interrupt input sensing.
  • GPIO_INSENSE_PRS - peripheral reflex system input sensing.
[in]maskMask containing bitwise logic OR of bits similar as for val used to indicate which input sense options to disable/enable.

__STATIC_INLINE void GPIO_IntConfig ( GPIO_Port_TypeDef  port,
unsigned int  pin,
bool  risingEdge,
bool  fallingEdge,
bool  enable 
)

Configure GPIO interrupt.

If reconfiguring a GPIO interrupt that is already enabled, it is generally recommended to disable it first, see GPIO_Disable().

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

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

Deprecated:
Deprecated function. New code should use GPIO_ExtIntConfig().
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().
Parameters
[in]portThe port to associate with pin.
[in]pinThe pin number on the port ( == GPIO EXTI interrupt number).
[in]risingEdgeSet to true if interrupts will be enabled on rising edge, otherwise false.
[in]fallingEdgeSet to true if interrupts will be enabled on falling edge, otherwise false.
[in]enableSet to true if interrupt will be enabled after configuration completed, false to leave disabled. See GPIO_IntDisable() and GPIO_IntEnable().
