static |
Clear the pending bit for an external interrupt.
- Parameters
-
IRQn The number of the interrupt for clear pending
Clear the pending bit for the specified interrupt. The interrupt number cannot be a negative value.
Definition at line 1557 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Decode the priority of an interrupt.
- Parameters
-
Priority The priority for the interrupt PriorityGroup The used priority group pPreemptPriority The preemptive priority value (starting from 0) pSubPriority The sub priority value (starting from 0)
Decode an interrupt priority value with the given priority group to preemptive priority value and sub priority value. In case of a conflict between priority grouping and available priority bits (__NVIC_PRIO_BITS) the samllest possible priority group is set.
The priority value can be retrieved with NVIC_GetPriority(...) function
Definition at line 1667 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Disable the interrupt line for external interrupt specified.
- Parameters
-
IRQn The positive number of the external interrupt to disable
Disable a device specific interupt in the NVIC interrupt controller. The interrupt number cannot be a negative value.
Definition at line 1517 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Enable Interrupt in NVIC Interrupt Controller.
- Parameters
-
IRQn The positive number of the external interrupt to enable
Enable a device specific interupt in the NVIC interrupt controller. The interrupt number cannot be a negative value.
Definition at line 1504 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Encode the priority for an interrupt.
- Parameters
-
PriorityGroup The used priority group PreemptPriority The preemptive priority value (starting from 0) SubPriority The sub priority value (starting from 0)
- Returns
- The encoded priority for the interrupt
Encode the priority for an interrupt with the given priority group, preemptive priority value and sub priority value. In case of a conflict between priority grouping and available priority bits (__NVIC_PRIO_BITS) the samllest possible priority group is set.
The returned priority value can be used for NVIC_SetPriority(...) function
Definition at line 1636 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Read the active bit for an external interrupt.
- Parameters
-
IRQn The number of the interrupt for read active bit
- Returns
- 1 = interrupt active, 0 = interrupt not active
Read the active register in NVIC and returns 1 if its status is active, otherwise it returns 0.
Definition at line 1571 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Read the interrupt pending bit for a device specific interrupt source.
- Parameters
-
IRQn The number of the device specifc interrupt
- Returns
- 1 = interrupt pending, 0 = interrupt not pending
Read the pending register in NVIC and return 1 if its status is pending, otherwise it returns 0
Definition at line 1531 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Read the priority for an interrupt.
- Parameters
-
IRQn The number of the interrupt for get priority
- Returns
- The priority for the interrupt
Read the priority for the specified interrupt. The interrupt number can be positive to specify an external (device specific) interrupt, or negative to specify an internal (core) interrupt.
The returned priority value is automatically aligned to the implemented priority bits of the microcontroller.
Note: The priority cannot be set for every core interrupt.

static |
Get the Priority Grouping from NVIC Interrupt Controller.
- Returns
- priority grouping field
Get the priority grouping from NVIC Interrupt Controller. priority grouping is SCB->AIRCR [10:8] PRIGROUP field.

static |
Set the pending bit for an external interrupt.
- Parameters
-
IRQn The number of the interrupt for set pending
Set the pending bit for the specified interrupt. The interrupt number cannot be a negative value.
Definition at line 1544 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Set the priority for an interrupt.
- Parameters
-
IRQn The number of the interrupt for set priority priority The priority to set
Set the priority for the specified interrupt. The interrupt number can be positive to specify an external (device specific) interrupt, or negative to specify an internal (core) interrupt.
Note: The priority cannot be set for every core interrupt.
Definition at line 1588 of file breezy/breezystm32/lib/CMSIS/CM3/CoreSupport/core_cm3.h.
|
static |
Set the Priority Grouping in NVIC Interrupt Controller.
- Parameters
-
PriorityGroup is priority grouping field
Set the priority grouping field using the required unlock sequence. The parameter priority_grouping is assigned to the field SCB->AIRCR [10:8] PRIGROUP field. Only values from 0..7 are used. In case of a conflict between priority grouping and available priority bits (__NVIC_PRIO_BITS) the smallest possible priority group is set.

Initialize and start the SysTick counter and its interrupt.
- Parameters
-
ticks number of ticks between two interrupts
- Returns
- 1 = failed, 0 = successful
