Hibernation Module
Description:
Clears the specified interrupt sources. This must be done from within the interrupt handler or
else the handler is called again upon exit.
The ui32IntFlags parameter has the same definition as the ui32IntFlags parameter to the
ROM_HibernateIntEnable() function.
Note:
Because there is a write buffer in the Cortex-M4 processor, it may take several clock cycles
before the interrupt source is actually cleared. Therefore, it is recommended that the interrupt
source be cleared early in the interrupt handler (as opposed to the very last action) to avoid
returning from the interrupt handler before the interrupt source is actually cleared. Failure to
do so may result in the interrupt handler being immediately reentered (because the interrupt
controller still sees the interrupt source asserted).
Returns:
None.
11.2.1.9 ROM_HibernateIntDisable
Disables interrupts for the Hibernation module.
Prototype:
void
ROM_HibernateIntDisable(uint32_t ui32IntFlags)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_HIBERNATETABLE is an array of pointers located at ROM_APITABLE[19].
ROM_HibernateIntDisable is a function pointer located at ROM_HIBERNATETABLE[22].
Parameters:
ui32IntFlags is the bit mask of the interrupts to be disabled.
Description:
Disables the specified interrupt sources from the Hibernation module.
The ui32IntFlags parameter has the same definition as the ui32IntFlags parameter to the
ROM_HibernateIntEnable() function.
Returns:
None.
11.2.1.10 ROM_HibernateIntEnable
Enables interrupts for the Hibernation module.
Prototype:
void
ROM_HibernateIntEnable(uint32_t ui32IntFlags)
