Field
31–11 Reserved, should be cleared.
10 DMA request level error. Indicates that the MDCR[DMAL] field was set to an invalid size and DMA requests are
DRL enabled (MDCR[DMA] = 1). The request level must be set to a value of 1-16 words. Zero is considered to be an
invalid request level
0 No error
1 Invalid DMA request level
9 Greater than data size error. Read only. Indicates that the GO bit was set in the MDCR and the data size written to
GTDS the MDDSR is greater then the amount of data written to the FIFO.
0 No error
1 Datasize is greater than the message size
8 Early read error. Read only. A context register was read from while the module was busy processing data.
ERE 0 No error
1 Early read error
7 Register modified during processing. Read only. An MDHA register was modified while the module was busy
RMDP processing data.
0 No error
1 Register modified
6 Reserved, should be cleared.
5 Illegal data size. Read only. Illegal data size was written to the MDHA Data Size Register (MDDSR). Data size written
DSE into the MDDSR is greater than the allocated size.
0 No error
1 Illegal data size in MDDSR
4 Illegal mode interrupt. Read only. Illegal mode is set in the MDMR. Consult
IME more information on invalid modes.
0 No error
1 Illegal value in MDMR
3 Reserved, should be cleared.
2 Non-empty input FIFO upon done. Read only. The Input FIFO contained data when processing was completed
NEIF 0 No error
1 FIFO contained data when finished processing
