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.
