* fs is a sampling frequency of input digital signal.
e.g.:sampling frequency 48kHz fs=48kHz
* 64fs and 256fs are 64 or 256 times the sampling frequency respectively.
e.g.: sampling frequency 48kHz
64fs: 48kHz x 64=3.072MHz
256fs: 48kHz x 256=12.288MHz
* The sampling frequency for analog input is fixed to 48kHz internally.
* (No.) indicates the pin number of individual.
* The arrow indicates the direction of signal as the input terminal pointed by
the arrow and the output terminal by the opposite.
