Functional Description of Register Bits
Unused bits
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.
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.
ITU-T/Sign Mag: When high, both Echo Cancellers A and B for a given group, accept ITU-T
(G.711) PCM code. When low, both Echo Cancellers A and B for a given group, accept sign-
magnitude PCM code.
A/
μ
Law: When high, both Echo Cancellers A and B for a given group, accept A-Law
companded PCM code. When low, both Echo Cancellers A and B for a given group, accept
μ
-
Law companded PCM code.
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+00
hex
to Base Address+3F
hex
, 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.
