Known Problem on using EOM Interrupt in combination with FIFO Lock in Run
Mode Slave:
In difference to the described behavior in Run Mode Slave NINT sticks low for low active
Interrupt or high for high active interrupt, after an EOM Interrupt, if FIFO Lock is enabled.
NINT is reset after reading the FIFO. See also
