division makes sense with the MSB of data value because the MSN of it holds the parity
code rather than useful data.
The sequence of data record during the reading operation is fixed. Normally, an application
will read 1st,.., 6th data record, the 7th and 8th data record would read only when it need to
fetch the configuration data. However, an application may apply a precharge command (see
Table
sequence 5th,.., 8th, 1st,.., 4th. Such change of sequence can be used to skip the first four
data records.
The timing diagram of the reading operation is shown on the
latching and beginning of shifting phase of the first byte (0x5F) of the first data record and
end of reading. Also, both alternatives to reset the internal transmission serial clock counter
is shown in signal SYN.
