W = : Only writing a 0 is effective; when you write a 1, the previous value is retained.
The DMA5-9 Interrupt Request Status Register lets you know the status of interrupt requests in
channels 5-9. If the DMAn interrupt request status bit (n = 5 to 9) is set to 1, it means that a DMAn
interrupt request in the corresponding channel has been generated.
DMITSTn (DMAn interrupt request status) bit (n = 5 to 9)
[Setting the DMAn interrupt request status bit]
This bit can only be set in hardware, and cannot be set in software.
[Clearing the DMAn interrupt request status bit]
This bit is cleared by writing a 0 in software.
Note: The DMAn interrupt request status bit cannot be cleared by writing a 0 to the
"Interrupt cause bit" of the DMA Interrupt Control Register that the interrupt
controller has.
When writing to the DMA5-9 Interrupt Request Status Register, be sure to set the bits you want to
clear to 0 and all other bits to 1. The bits which are thus set to 1 are unaffected by writing in
software, and retain the value they had before you wrote.
