7 / 24 page  1998 Jan 06 7 Philips Semiconductors Product specification Noise shaping filter DAC TDA1386T 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.
