26.5.7.7 DEU Interrupt Mask Register (DEUIMR)
The Interrupt Mask Register controls the result of detected errors. For a given error (as defined in
Section 26.4.2.6, DEU Interrupt Status Register, on page 26-39), if the corresponding bit in this
register is set, then the error is ignored; no bit is set in the DEU Interrupt Status Register, and no
error interrupt occurs. If the corresponding bit is not set, then upon detection of an error, the

Input FIFO Underflow
If set, the DEU input FIFO was read while
empty.
0
No input FIFO underflow error detected.
1
Input FIFO underflow error.
IFO

0
Input FIFO Overflow
If set, the DEU input FIFO was pushed while
full.
Note:
When operated through
channel-controlled access, the SEC
implements flow control, and FIFO
size is not a limit to data input. When
operated through core processor-
controlled access, the DEU cannot
accept FIFO inputs larger than 256
bytes without overflowing.
0
No input FIFO overflow error detected.
1
Input FIFO overflow error.

Output FIFO Underflow
If set, the DEU output FIFO was read while

Output FIFO Overflow
If set, the DEU output FIFO was pushed while
