The Sign-bit extended mode is entered by applying a logic “0” to the BCLKR pin while all other clocks
are clocked normally. In standard 13-bit mode the first bit is the sign bit. In this mode the device
transmits and receives 16-bit data where the sign bit is extended to the first four data bits. The PCM
timing for this mode is illustrated below.
The Receive Path Adjust Mode is entered by applying a logic “1” to the BCLKR pin while all other
clocks are clocked normally. In this mode the device receives 16-bit data where the last three bits are
coefficients to program the Receive Gain Adjust Attenuation described above. The PCM timing for
this mode is illustrated below.
