The Transaction MAC is not updated when the TransactionMAC file is targeted with the

ReadData command.

WriteData command TMI update

TMI = TMI || Cmd || FileNo || Offset || Length || ZeroPadding || Data ||

ZeroPadding

Note that the first ZeroPadding for the WriteData command is actually adding 8 zero

bytes after the command parameter fields so that those and the padding add up to 16

bytes.

GetValue command TMI update

TMI = TMI || Cmd || FileNo || Value || ZeroPadding

Credit command TMI update

TMI = TMI || Cmd || FileNo || Value || ZeroPadding

Debit command TMI update

TMI = TMI || Cmd || FileNo || Value || ZeroPadding

LimitedCredit command TMI update

TMI = TMI || Cmd || FileNo || Value || ZeroPadding

ReadRecords command TMI update

TMI = TMI || Cmd || FileNo || RecNo || RecCount || ZeroPadding || Data

If RecCount is set to 000000h in the command, meaning that all records are read

(starting from the RecNo), the actual length value is filled in with the number of records

read for the TM computation.

Note that ZeroPadding for the ReadRecords command is actually adding 8 zero bytes

after the command parameter fields so that those and the padding add up to 16 bytes. As

the data is always a multiple of 16 bytes, no padding is needed at the end of the TMI.

WriteRecord command TMI update

TMI = TMI || Cmd || FileNo || Offset || Length || ZeroPadding || Data

Note that ZeroPadding for the WriteRecord command is actually adding 8 zero bytes

after the command parameter fields so that those and the padding add up to 16 bytes. As

the data is always a multiple of 16 bytes, no padding is needed at the end of the TMI.

UpdateRecord command TMI update

TMI = TMI || Cmd || FileNo || RecNo || Offset || Length || ZeroPadding || Data

Note that ZeroPadding for the UpdateRecord command is actually adding 5 zero bytes

after the command parameter fields so that those and the padding add up to 16 bytes. As

the data is always a multiple of 16 bytes, no padding is needed at the end of the TMI.

ClearRecordFile command TMI update

TMI = TMI || Cmd || FileNo || ZeroPadding
