MICROCONTROLLER APPLICATION MODE

(APPL = LOGIC 1, APP3 = LOGIC 0)

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.

MICROCONTROLLER 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.
