Notes:
 Reading registers from addresses not listed in this table results in 0x02 exception.
 Specifying an incorrect or out-of-range parameter value results in entering the value
0xEEEE into the command register.
 The device is configured by writing three registers (password / command /
parameter) at the same time using the 0x10 function with the corresponding values
– according to the command table, or by writing single registers (using 0x06 or 0x10
function) with the latter writing of a (valid) password causing the execution of the
command.
 During a single password entry (both with function 0x06 and 0x10) in case of a
password match, the correctness of information in command and parameter
registers is checked and if correct, the command is executed.
