Internal digital control, serial bus and external
digital input signal relationships
The settings of all internal switches, DACs and modes of
operationcanbeprogrammedviatheserialbus.Thereare
also a few external digital signals which influence the
programmed settings.
7.4.1
STANDBY
MODE
Toensureasafestart-up, theTZA1038HW hasaninternal
Power-on reset that resets on bit PWRON. During
STANDBY mode, most circuits, including laser supplies,
are switched off.
bit CD_LDON = 1 if CD laser is on and POWERON
bit DVD_LDON = 1 if DVD laser is on and POWERON.
7.4.2
RF
ONLY MODE
The servo outputs can be disabled for easy interfacing in
systems where two front-end signal processors are used.
This mode will set the outputs OA to OD, S1 and S2 to
3-state. The RF data path remains active.
