6.3.5. Register MODE_REG
Note: The use of this register is no longer recom-
As soon as this register is applied, the MSP 34x0G
works in the MSP 34x0D Manual/Compatibility
Mode. In this mode, BTSC, EIA-J, and FM-Radio are
disabled. Only MSP 34x0D features are available; the
use of MODUS and STATUS register is not allowed.
The MSP 34x0G 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 34x0G in
the MSP 34x0D Manual/Compatibility Mode; Table 6–
12 explains all bit positions.

software compatibility to the MSP 34x0D is

vides a more economic way to program the
