ML6411

RESET DEFAULT MODE

The ML6411 provides a RESET pin that programs the

Control Registers as described in Table 8. The RESET pin is

active HIGH. Basically, the ML6411 on RESET defaults to:

S-Video mode. Ideally, for PAL S-Video since Preset

Mode (STDA and STDB bits) is set to unity gain boost

(GPRESET = 1) for both Y and C (see Table 2)

Y is clamped to 16. C is clamped to 128 (see Table 3)

and CLPA and CLPB bits)

FUNCTIONAL DESCRIPTION (Continued)

UGC is set to unity gain (GUGCA = 1 and GUGCB = 1) to

either Y or C channels (see Table 4 and GNA and GNB

bits)

Input pin are set for 2VP-P inputs on both Y and C
