the interrupt source, even if the interrupt is masked, can be read in ISR.
DRQ interrupt request is cleared by reading (reception) or writing (transmission) FIFO, other
interrupt requests are cleared by writing 1 to the corresponding bit in Interrupt Status Clear Reg-
ister (ISCR).
There is no OCD mode for MSI.
