UART
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.
22.2.1.27 ROM_UARTIntDisable
Disables individual UART interrupt sources.
Prototype:
void
ROM_UARTIntDisable(uint32_t ui32Base,
uint32_t ui32IntFlags)
ROM Location:
ROM_APITABLE
is an array of pointers located at
0x0100.0010
.
ROM_UARTTABLE
is an array of pointers located at
ROM_APITABLE[1]
.
ROM_UARTIntDisable
is a function pointer located at
ROM_UARTTABLE[18]
.
Parameters:
ui32Base
is the base address of the UART port.
ui32IntFlags is the bit mask of the interrupt sources to be disabled.
Description:
Disables the indicated UART interrupt sources. Only the sources that are enabled can be
reflected to the processor interrupt; disabled sources have no effect on the processor.
The ui32IntFlags parameter has the same definition as the ui32IntFlags parameter to
ROM_UARTIntEnable() .
Returns:
None.
22.2.1.28 ROM_UARTIntEnable
Enables individual UART interrupt sources.
Prototype:
void
ROM_UARTIntEnable(uint32_t ui32Base,
uint32_t ui32IntFlags)
ROM Location:
ROM_APITABLE
is an array of pointers located at
0x0100.0010
.
ROM_UARTTABLE
is an array of pointers located at
ROM_APITABLE[1]
.
ROM_UARTIntEnable
is a function pointer located at
ROM_UARTTABLE[17]
.
Parameters:
ui32Base is the base address of the UART port.
