Functional Description of Register Bits
These peak detector registers allow the user to monitor the error signal peak level. The information is in 16 bit
2’s complement linear coded format presented in two 8 bit registers for each echo canceller. The high byte is in
Register 2 and the low byte is in Register 1.

Functional Description of Register Bits
This register allows the user to program the level of Double-Talk Detection Threshold (DTDT). The 16 bit 2’s
complement linear value defaults to 4800hex= 0.5625 or -5 dB. The maximum value is 7FFFhex = 0.9999 or
0 dB. The high byte is in Register 2 and the low byte is in Register 1.
