Table 4. Register Settings for Looping VCR Signals to the TV
Note 5: TV slow-switch output (bits 1 and 0) should be the same as VCR slow-switch input.
Note 6: User has to set bits 7 and 3 appropriately depending upon whether signal is red or chroma.
All circuitry is shut down in the MAX9598 except for the

Except for register 10h, which sets the operating mode,
the values in all the other I
while entering, during, and leaving shutdown mode.
Put the MAX9598 into low-power mode during standby.
Everything is shut down except for the slow-switching
circuits, CVBS input detection, CVBS load detection,
and I
active low whenever the slow-switch signal changes; a
CVBS signal appears or disappears; or a CVBS load
appears or disappears. The µC in the set-top box can
then decide whether to change the MAX9598 to full-
power mode and loop VCR signals to the TV.
Before entering low-power mode, the slow-switch sig-
nals should be set to high impedance.

0Eh and 0Fh might change in low-power mode because
they provide status on the slow switch signals, CVBS
input, and CVBS outputs. The value in register 10h
changes while entering or leaving low-power mode
because bits 6 and 7 set the operating mode.
In this mode, the MAX9598 is fully on. If interrupt is
enabled, then INT will go active low whenever the slow-
switch signal changes; a CVBS signal appears or dis-
appears; or a CVBS load appears or disappears. The
µC can decide whether to change the routing configu-
ration or operating mode of the MAX9598.
This mode is similar to the above mode except that
video input detection and video load detection are not
active. If interrupt is enabled, then INT will go active low
only when the slow-switch signal changes.
