The ramp-down register sets the hold-off and fade-off
times and allows hold-off and fade-off to be disabled
(zero delay), if desired
sets the ramp-up time and allows ramp-up to be dis-
abled (zero delay), if desired
tion register contains 3 status bits that identify whether
the MAX6966/MAX6967 are in hold-off, fade-off, or ramp-
up condition
enables or disables ramp-up. One write to the configura-
tion register can put the MAX6966/MAX6967 into shut-
down (using hold-off and fade-off settings in the fade
