Note:
NICAM decoding can be achieved by using the
MSP 3410 instead of the MSP 3400C. Since the
MSP 3400C and the MSP 3410 are fully pin and soft-
ware downwards compatible (concerning all features of
MSP 3410), it is possible to decide in the assembly line,
whether the application should be able to decode
NICAM or not.
