13.2.1 Function Documentation
13.2.1.1 ROM_IntDisable
Disables an interrupt.
Prototype:
void
ROM_IntDisable(uint32_t ui32Interrupt)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_INTERRUPTTABLE is an array of pointers located at ROM_APITABLE[14].
ROM_IntDisable is a function pointer located at ROM_INTERRUPTTABLE[3].
Parameters:
ui32Interrupt specifies the interrupt to be disabled.
Description:
The specified interrupt is disabled in the interrupt controller. Other enables for the interrupt
(such as at the peripheral level) are unaffected by this function.
Returns:
None.

Enables an interrupt.
Prototype:
void
ROM_IntEnable(uint32_t ui32Interrupt)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_INTERRUPTTABLE is an array of pointers located at ROM_APITABLE[14].
ROM_IntEnable is a function pointer located at ROM_INTERRUPTTABLE[0].
Parameters:
ui32Interrupt specifies the interrupt to be enabled.
