Decoder Sampling Frequency Set Register. The sampling time (ts) is 1÷(sampling
frequency). The voice data get out every ts and interpolation data get out between
every the voice data.
ex) data1, (data1+data2)/2, data2, (data2+data3)/2, -----.

Decoder Bundle Size. This value should be greater than 6. If this value is
“00”, the
bundle size is 256-bytes. This value should be same with encoder
’s bundle size.
