uDMA Controller
Parameters:
ui32ChanMask
is a 32-bit mask with one bit for each uDMA channel.
Description:
Clears bits in the uDMA interrupt status register according to which bits are set in
ui32ChanMask
. There is one bit for each channel. If a a bit is set in
ui32ChanMask
, then
that corresponding channel’s interrupt status is cleared (if it was set).
Returns:
None.
23.2.1.24 ROM_uDMAIntStatus
Gets the uDMA controller channel interrupt status.
Prototype:
uint32_t
ROM_uDMAIntStatus(void)
ROM Location:
ROM_APITABLE
is an array of pointers located at
0x0100.0010
.
ROM_UDMATABLE
is an array of pointers located at
ROM_APITABLE[17]
.
ROM_uDMAIntStatus
is a function pointer located at
ROM_UDMATABLE[19]
.
Description:
This function is used to get the interrupt status of the uDMA controller. The returned value
is a 32-bit bit mask that indicates which channels are requesting an interrupt. This function
can be used from within an interrupt handler to determine or confirm which uDMA channel has
requested an interrupt.
Returns:
Returns a 32-bit mask which indicates requesting uDMA channels. There is a bit for each
channel, and a 1 in a bit indicates that channel is requesting an interrupt. Multiple bits can be
set.
