FILTERS
If CALS is reset during CALR = 0, the calibration will be
stopped if it was not finished yet. If required, a new
calibration can be started using CALS.
WARNING:
the IC should not be calibrated in a test or
standby mode.
6.3.4
PAL/NTSC
MODE
Depending on bit NTSC the IC is calibrated in PAL or
NTSC mode using bit CALS. After an automatic calibration
the oscillator frequencies can be switched between PAL
and NTSC using bit NTSC. This centre frequency shift is
done without automatic calibration. During playback (PB)
or loop-through (LT) a change in bit NTSC will
automatically calibrate the bandpass filters again. This will
take <10 ms.
WARNING:
A change of PB to REC, LT to REC and
PAL to NTSC should not be combined in one transmitted
byte. The PAL to NTSC transition should be preceded by
the PB to REC or LT to REC transition.

C-bus
The TDA9614H is controlled via the 2-wire I
2
C-bus, in
accordance with the I
2
C-bus specification. As slave
receiver for programming there is one module address,
with R/W bit = 0, a subaddress byte and eight data bytes.
If more than one data byte follows the subaddress, these
bytes are stored in the successive registers by the
automatic address increment feature. As slave transmitter
(R/W bit = 1) there is one read byte.
