Tone Disabler Masks 2 Register
The bits in this register are used to mask conditions from automatically enabling clear channel operation when the
condition is detected. The provisioning of the mask is for all channels, but the action is per-channel.
Used in conjunction with other tone detector mask bits to create the global conditions for selecting what tone detec-
tion options control whether the echo canceller is enabled on a particular channel.
