Information

The state of any given channel’s interrupt request is directly affected by writes to this
register; it is also affected by writes to the CINT register. On writes to INT, a 1 in any bit
position clears the corresponding channel’s interrupt request. A zero in any bit position
has no affect on the corresponding channel’s current interrupt status. The CINT register is
provided so the interrupt request for a single channel can easily be cleared without the
need to perform a read-modify-write sequence to the INT register.
Address: DMA_INT is 4000_8000h base + 24h offset = 4000_8024h
