W= : Only writing 0 is effective. Writing 1 has no effect, the bit retains the value it had before writing.
The DMA5-9 Interrupt Request Status Register helps to know the status of interrupt requests on
DMA channels 5-9. If the DMAn interrupt request status bit (n = 5-9) is set to 1, it means that the
channel has a DMA interrupt request generated.
DMITSTn (DMAn interrupt request status) bit (n = 5-9)
The DMAn interrupt request status bit is set in hardware, and cannot be set in software.
The DMAn interrupt request status bit is cleared by writing 0 in software.
Note: The DMAn interrupt request status bit is not cleared by writing 0 to the DMA Interrupt
Control Register "interrupt request bit" of the Interrupt Controller.
When writing to the DMA5-9 Interrupt Request Status Register, be sure to write 0 for the bits to be
cleared and 1 for all other bits. Writing 1 in software does not affect any bit of this register, the bit
retains the value it had before writing.
