When "input signal mode" is "external 8fs data mode", regardless of a setup of EXIOSEL pin, the data of 8fs rate are

inputted from EXDATAL, EXDATAR pins.

By setup of serial control "System1 mode:bit21", Primary Side Synchronous Input or Secondary Side Synchronous

Input can be selected.

In case an external 8fs data input is secondary side synchronous , the data is inputted to Gain Control Block.
