6.3.5. Register MODE_REG
Note:
The use of this register is no longer recom-
mended. It should be used only in cases where soft-
ware compatibility to the MSP 34x5D is required.
Using the STANDARD SELECTION register together
with the MODUS register provides a more economic
way to program the MSP 34x5G.
As soon as this register is applied, the MSP 34x5G
works in the
MSP 34x5D Manual/Compatibility
Mode
. In this mode,
BTSC, EIA-J, and FM-Radio are
disabled
. Only MSP 34x5D features are available; the
use of MODUS and STATUS register is not allowed.
The MSP 34x5G is reset to the normal mode by first
programming the MODUS register, followed by trans-
mitting a valid standard code to the STANDARD
SELECTION register.
The register
MODE_REG
contains the control bits
determining the operation mode of the MSP 34x5G in
the MSP 34x5D Manual/Compatibility Mode; Table 6
12
explains all bit positions.

For signals above 1.4 Vpp, the minimum gain of 3 dB is switched, and overflow of the A/D converter may result. Due to the
robustness of the internal processing, the IC works up to and even more than 3 Vpp, if norm conditions of FM/NICAM or
FM1/FM2 ratio are supposed. In this overflow case, a loss of FM-S/N-ratio of about 10 dB may appear.
