12.4.4.9
The MDEU ICV size register, shown in
compared if the MDEU performs ICV comparison. (See
(MDEUMR).”)
This register is cleared when the MDEU is reset or re-initialized.
12.4.4.10 MDEU EU Go Register (MDEUEUG)
The EU go register in the MDEU, see
completed. After the final message block is written to the input FIFO, the EU go register must be written.
The value in the data size register is used to determine how many bits of the final message block (always
512) is processed. Note that this register has no data size, and during the write operation, the host data bus
is not read. Hence, any data value is accepted. Normally, a write operation with a zero data value is
performed. Reading from this register is not meaningful, but a zero value is always returned, and no error
is generated. Writing to this register is merely a trigger causing the MDEU to process the final block of a
message, allowing it to signal DONE.
