2fs output format

There are two 2fs output formats that can be set using FMT2FS. The output data is in 32-bit 2s complement

format.

However, when external inputs (EXID1, EXID2, EXILRCK, EXIBCK) are selected, the signals are output as-

is in through mode regardless of the format setting.

(1) MSB-first left-justified 32-bit (FMT2FS = “L”)

I

If more than 32 bit clock cycles are input during each word clock cycle HIGH-level or LOW-level interval,

data following the 32nd bit are output as “0”.

I

When F2LRCK and F2BCK are set as outputs, there are 32 fixed bit clock cycles per word clock cycle

HIGH-level or LOW-level interval.

(2) IIS 32-bit (FMT2FS = “H”)

I

In this format, there are 32 bit clock cycles per word clock cycle regardless of the input/output settings.
