TXD
This method allows the user to create an own programming sequence by choosing the programming bytes and the number of
them. The programming sequence has to be provided to the master.
General Call

GENERAL CALL
GENERAL CALL
0000000 + W
The general call is performed in order to change the address of the slave.
If a GENERAL CALL is detected, GACC is set.
After the detection of General Call, it is up to the programmer to decode the commands which
come afterwards.
In case of a WRITE command, the programmer has to decode the programming sequence and
program a new SADR if the programming sequence matches.
