AUDIO SIGNAL PROCESSOR
APPLICATION INFORMATION
Logic Part
First of all, if you let the MICOM operate, pin 25 has to connect to the GND.
The S1A0293A obtains the MICOM data such as the following: timing diagram, and then, converts the data from
serial to parallel type by the use of internal analog switches.
The signal input from MICOM, consists of the 12-bit serial data, and the data consists of the 4-bit address and the
8-bit data for the selection of the switch input.
