Short-
Programming
0020
Write into this register to apply Demodulator Short Programming (see
section 6.4.1.). If the internal setting coincidences with the individual re-
quirements no more of the remaining Demodulator Write Registers have
to be transferred.
AUTO_FM/AM
0021
Only for NICAM (MSP 3415D): Automatic switching between NICAM and
FM/AM in case of bad NICAM reception (see section 6.4.2.)
Write Registers necessary for General Programming Mode only
