Nested Vector Interrupt Controller (NVIC) functions related to TrustZone for Armv8-M.
void TZ_NVIC_ClearPendingIRQ_NS | ( | IRQn_Type | IRQn | ) |
Clear Pending Interrupt (non-secure)
Clears the pending bit of an non-secure external interrupt when in secure state.
[in] | IRQn | External interrupt number. Value cannot be negative. |
void TZ_NVIC_DisableIRQ_NS | ( | IRQn_Type | IRQn | ) |
Disable External Interrupt (non-secure)
Disables a device-specific interrupt in the non-secure NVIC when in secure state.
[in] | IRQn | External interrupt number. Value cannot be negative. |
void TZ_NVIC_EnableIRQ_NS | ( | IRQn_Type | IRQn | ) |
Enable External Interrupt (non-secure)
Enables a device-specific interrupt in the non-secure NVIC when in secure state.
[in] | IRQn | External interrupt number. Value cannot be negative. |
uint32_t TZ_NVIC_GetActive_NS | ( | IRQn_Type | IRQn | ) |
Get Active Interrupt (non-secure)
Reads the active register in non-secure NVIC when in secure state and returns the active bit.
[in] | IRQn | Interrupt number. |
uint32_t TZ_NVIC_GetEnableIRQ_NS | ( | IRQn_Type | IRQn | ) |
Get Interrupt Enable status (non-secure)
Returns a device specific interrupt enable status from the non-secure NVIC interrupt controller when in secure state.
[in] | IRQn | Interrupt number. |
uint32_t TZ_NVIC_GetPendingIRQ_NS | ( | IRQn_Type | IRQn | ) |
Get Pending Interrupt (non-secure)
Reads the pending register in the non-secure NVIC when in secure state and returns the pending bit for the specified interrupt.
[in] | IRQn | Interrupt number. |
uint32_t TZ_NVIC_GetPriority_NS | ( | IRQn_Type | IRQn | ) |
Get Interrupt Priority (non-secure)
Reads the priority of an non-secure interrupt when in secure state. The interrupt number can be positive to specify an external (device specific) interrupt, or negative to specify an internal (core) interrupt.
[in] | IRQn | Interrupt number. |
uint32_t TZ_NVIC_GetPriorityGrouping_NS | ( | void | ) |
Get Priority Grouping (non-secure)
Reads the priority grouping field from the non-secure NVIC when in secure state.
void TZ_NVIC_SetPendingIRQ_NS | ( | IRQn_Type | IRQn | ) |
Set Pending Interrupt (non-secure)
Sets the pending bit of an non-secure external interrupt when in secure state.
[in] | IRQn | Interrupt number. Value cannot be negative. |
void TZ_NVIC_SetPriority_NS | ( | IRQn_Type | IRQn, |
uint32_t | priority | ||
) |
Set Interrupt Priority (non-secure)
Sets the priority of an non-secure interrupt when in secure state.
[in] | IRQn | Interrupt number. |
[in] | priority | Priority to set. |
void TZ_NVIC_SetPriorityGrouping_NS | ( | uint32_t | PriorityGroup | ) |
Set Priority Grouping (non-secure)
Sets the non-secure priority grouping field when in secure state using the required unlock sequence. The parameter PriorityGroup 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.
[in] | PriorityGroup | Priority grouping field. |
