Format Control
The digital data input format is selected via three external terminals (FORMAT0, FORMAT1, and FORMAT2).
Table 1 lists the corresponding data format for SDIN1 and SDIN2. LRCLK and SCLK are shared clocks for
SDIN1 and SDIN2. Changes to the FORMATx terminals are latched in immediately on a rising edge of RESET.
Changes to the FORMATx terminals while RESET is high are not allowed.

Gain Control
The gain of the DAP is selected via two external gain pins (GAIN_0 and GAIN_1). Table 2 lists the corresponding
channel gain (for ALL channels) for GAIN_0 and GAIN_1 settings. Individual channel gain is not possible.
Changes to the GAIN_x terminals are latched in immediately on a rising edge of RESET. Changes to the
GAIN_x terminals while RESET is high are not allowed.
