| #define | IFX_INTERRUPT(isr, vectabNum, prio) |
| Macro to define Interrupt Service Routine. This macro makes following definitions: 1) Define linker section as .intvec_tc<vector number>_<interrupt priority>. 2) define compiler specific attribute for the interrupt functions. 3) define the Interrupt service routine as Isr function.

| IFX_INLINE boolean IfxCpu_areInterruptsEnabled | ( | void | ) |
API to get the status of global interrupt enable (ICR.IE) for the CPU which calls this API This API provides the status of CPU where this API is called.
- Returns
- Status of global interrupt enable bit.
- Return values
-
TRUE,: Global interrupts enabled. FALSE,: Global interrupts disabled

| IFX_INLINE boolean IfxCpu_disableInterrupts | ( | void | ) |
API to disable global interrupt and return the previous status.
This API can be used only to disable the global interrupts of caller CPU. It cannot be used for this activity towards other CPUs
- Returns
- Previous status of global interrupt enable bit.
- Return values
-
TRUE,: Previously, global interrupts enabled. FALSE,: Previously, global interrupts disabled
