21.6.3 DMA Interrupt Terminal Count Request Clear Register
The INTTCCLEAR Register is write-only and clears one or more terminal count interrupt
requests. When writing to this register, each data bit that is set HIGH causes the
corresponding bit in the status register (IntTCStat) to be cleared. Data bits that are LOW
have no effect.
21.6.4 DMA Interrupt Error Status Register
The INTERRSTAT Register is read-only and indicates the status of the error request after
masking.
21.6.5 DMA Interrupt Error Clear Register
The INTERRCLR Register is write-only and clears the error interrupt requests. When
writing to this register, each data bit that is HIGH causes the corresponding bit in the
status register to be cleared. Data bits that are LOW have no effect on the corresponding
bit in the register.

INTTCCLEAR Allows clearing the Terminal count interrupt request
(IntTCStat) for DMA channels. Each bit represents one
channel:
0 - writing 0 has no effect.
1 - clears the corresponding channel terminal count
interrupt.
