C-bus interface for colour decoders
TDA8442
OPERATION
Write
The TDA8442 is controlled via the I
2
C-bus (specifications for the I
2
C-bus will be supplied on request).
Programming of the TDA8442 is performed using the format shown in Fig.3.
Acknowledge (A) is generated by the TDA8442 only when a valid address is received and the device is not in the
power-down-reset mode (V
P
> 8.5 V (typ.)).
Control
Control is implemented by the instruction bytes POD (port output data) and DACX (digital-to-analogue converter control)
together with the corresponding data/control bytes (see Fig.4).
POD bit P1
If a logic 1 is programmed, the P1 output is switched on. If a logic 0 is programmed or after a power-down-reset, the P1
output is switched off (high-impedance state).
POD bit P2/P2N
If a logic 1 is programmed, the P2 output is switched off and the P2N output is switched on (LOW). If a logic 0 is
programmed or after a power-down-reset, the P2 output is switched on (LOW) and the P2N output is switched off.
DAX bits AX5 to AX0
The digital-to-analogue converter selected corresponds to the decimal equivalent of the two bits X1 and X0. The output
voltage of the selected DAC is programmed using bits AX5 to AX0, the lowest value being with all data AX5 to AX0 at
logic 0 or when power-down-reset has been activated.
