In this mode, the device operation is controlled by a set of
flags in an 8-bit mode control register. The 8-bit mode
control register is written by a microprocessor interface
(pin APPL = 1, APP0 = Data, APP1 = Clock, APP2 = RAB
and APP3 = 0).
The correspondence between serial to parallel conversion,
mode control flags and a summary of the effect of the
control flags is given in Table 3. Figures 3 and 4 illustrate
the mode set timing.

ICROCONTROLLER WRITE OPERATION SEQUENCE
APP2 is held LOW by the microcontroller.
Microprocessor data is clocked into the internal shift
register on the LOW-to-HIGH transition at pin APP1.
Data D(7 to 0) is latched into the appropriate control
register on the LOW-to-HIGH transition of pin APP2
(with APP1 HIGH).
If more data is clocked into the TDA1386T before the
LOW-to-HIGH transition on pin APP2 then only the last
8 bits are used.
If less data is clocked into the TDA1386T unpredictable
operation will result.
If the LOW-to-HIGH transition of pin APP2 occurs with
APP1 LOW, the command will be disregarded.
