Refer to Programmers Model with TrustZone for more information. Clear Interrupt Target State. The priority specifies the interrupt priority value, whereby lower values indicate a higher priority. Clears the interrupt target field in the non-secure NVIC when in secure state. The returned priority value is automatically aligned to the implemented priority bits of the microcontroller.

A summary of the source files within the library is as follows Usage Fault Interrupt [not on Cortex-M0 variants]. The Vector Table defines the entry addresses of the processor exceptions and the device specific interrupts.

Secure Fault Interrupt [only on Armv8-M]. Set a device specific interrupt to pending.

Writes to unimplemented bits are ignored. For the actual details of the MCU setup, you should read the code supplied in these files in conjunction with the MCU user manual.

Note that when you create a llpc CMSIS using project, if the appropriate CMSIS library does not exist in the workspace, you will get an error message and the project will not be created. IRQn must not be negative. Other processor variants may have fewer vectors. This function reads the priority for the specified interrupt IRQn.

At the beginning of cmmsis vector table, the initial stack value and the exception vectors of the processor are defined.

Parameters [in] IRQn External interrupt number. Supports 0 to priority levels. The core exception enumeration names for IRQn values are defined in the file device. HardFault and NMI have a fixed negative priority that is higher than any cmis exception or interrupt. Set Interrupt Target State. This function sets the pending bit for the specified device specific interrupt IRQn. All device specific interrupts should have a default interrupt handler function that loc be overwritten in user code.

Enable a device specific cmeis. Each register can be further devided into preempt priority level and subpriority level.

Get the pending device specific interrupt.

Each Interrupt Priority Level Register is 1-byte wide. The priority specifies the interrupt priority value, whereby lower values indicate a higher priority. Refer to Programmers Model ccmsis TrustZone for more information.

Clears the interrupt target field in the non-secure NVIC when in secure state. This function returns the interrupt enable status for the specified device specific interrupt IRQn.

This function encodes the priority for an interrupt with the priority group PriorityGrouppreemptive priority value PreemptPriorityand subpriority value SubPriority.

This function enables the specified device specific interrupt IRQn. Definition of IRQn numbers. The priority cannot be set for every core interrupt. Get a device specific interrupt enable status.

**** Advance Notice ****

IRQn cannot be a negative number. The function sets the priority grouping PriorityGroup using the required unlock sequence. When you choose to create a CMSIS-based project, the wizard will make a number of modifications to all build configurations of the project that it creates:
