26.2.6
The MDDSR stores the size of the last block of data to be processed. This value is in bytes. The
first two bits are used to identify the ending byte location in the last word. This is used to add the
data padding when auto padding is selected in the MDMR. Load this register with the amount of
data to be processed in the FIFO. This register is cleared when the MDHA is reset, re-initialized
and at the end of processing the complete message.

Illegal data size. Read only. Illegal data size was written to the MDHA Data Size Register
(MDDSR). Data size written into the MDDSR is greater than the allocated size.
0 No error
1 Illegal data size in MDDSR
Illegal mode interrupt. Read only. Illegal mode is set in the MDMR. Consult
Section 26.2.1.1, “Invalid Modes,”
0 No error
1 Illegal value in MDMR
Reserved, should be cleared.
Non-empty input FIFO upon done. Read only. The Input FIFO contained data when
processing was completed
0 No error
1 FIFO contained data when finished processing
