Program the SCART video and audio switches by writ-
ing to registers 00h through 0Dh (Tables 3 through 18).
Registers 00h through 0Dh can also be read, allowing
read-back of data after programming and facilitating
system debugging. The status register is read-only and
can be read from address 0Eh (Table 19).

The DAC outputs of encoder chips need to be
processed through a lowpass filter (reconstruction filter)
to attenuate out-of-band noise. Figure 9 shows how the
MAX7440 provides an integrated, convenient solution for
reconstruction filtering.
