Bit 15
Echo Cancellation Control (for DTMF Detection).
Echo cancellation improves the performance of DTMF detection during playback. Echo cancellation
can be turned on only with a system that can disable HW AGC (if present) during playback. A system fea-
turing HW AGC, that cannot be controlled by the microcontroller (i.e., disabled or enabled), must not turn
on this bit.
Bit 16
Clock bit rate (in Slave Mode only).
Bit 17
