Functional Description of Register Bits

Unused Bits.
MTDBI
Mask Tone Detector B Interrupt: When high, the Tone Detector interrupt output from Echo Canceller
B is masked. The Tone Detector operates as specified in Echo Canceller B, Control Register 2.
When low, the Tone Detector B Interrupt is active.
MTDAI
Mask Tone Detector A Interrupt: When high, the Tone Detector interrupt output from Echo Canceller
A is masked. The Tone Detector operates as specified in Echo Canceller A, Control Register 2.
When low, the Tone Detector A Interrupt is active.
Format
ITU-T/Sign Mag: When high, both Echo Cancellers A and B for a given group, select ITU-T (G.711)
PCM code. When low, both Echo Cancellers A and B for a given group, select sign-magnitude PCM
code.
Law
A/
Law: When high, both Echo Cancellers A and B for a given group, select A-Law companded
PCM code. When low, both Echo Cancellers A and B for a given group, select
-Law companded
PCM code.
PWUP
Power-UP: When high, both Echo Cancellers A and B and Tone Detectors for a given group, are
active. When low, both Echo Cancellers A and B and Tone Detectors for a given group, are placed
in Power Down mode. In this mode, the corresponding PCM data are bypassed from Rin to Rout
and from Sin to Sout with two frames delay. When the PWUP bit toggles from zero to one, the
echo cancellers A and B execute their initialization routine which presets their registers, Base
Address+00hex to Base Address+3Fhex, to default Reset Value and clears the Adaptive Filter
coefficients. Two frames are necessary for the initialization routine to execute properly. Once the
initialization routine is executed, the user can set the per channel Control Registers for their specific
application.
