These interrupts are per channel interrupts, as shown in
Table
register per channel. There are no dedicated storage of
these channel interrupts. Once each Channel’s Interrupts’
are clear, the associated channel interrupt is clear.
Note: The order of the internal M2P channel interrupts is
for compatibility reasons with previous versions of
software.
