DESCRIPTION
Following is an example of the Block Write-Block Read Process Call. The Block Write-Block Read
Process Call is a two-part message. It begins with a salve address and a write condition. After the
command code the host issues a write count M that describes how many more bytes will be written in
the first part of the message. The second part of the message is a block of read data beginning with a
repeated start condition followed by thee salve address and a Read Bit. The next read byte count N
indicates how many more data will be read in the second part of the message. Note that the combined
data payload must not exceed 32bytes. Besides, W83791D/G also provides packet error code (PEC)
to insure the accuracy during data transmission.
