ADDRESS 25h is RESERVED
Addresses: 27h to 2Dh are transmit and receive gains and coefficients used by the filters in the handsfree
decision circuit.
2Eh to 3Fh are scratch-pad ram locations used by the DSP algorithms as temporary storage dur-
ing calculations.
This register is used to program the low-group frequency of the DTMF program. The tone coefficient is calculated as follows:
COEF = 0.128 x Frequency
where: Frequency is in Hz (note: COEF must be converted to an 8 bit binary integer)
Highest frequency possible:
1992.2 Hz
Lowest frequency possible:
7.8 Hz
Frequency resolution:
7.8 Hz
Pre-twist:
-2.1dB ± 0.2dB
This register is used to program the first frequency of the squarewave ringer program. The tone coefficient is calculated as follows:
COEF = 8000 / Frequency
where: Frequency is in Hz (note: COEF must be rounded off and converted to an 8 bit binary integer)
Highest frequency possible:
4000 Hz
Lowest frequency possible:
31.4 Hz
Frequency resolution:
non-linear

The tone ringer will switch between squarewave frequencies at a warble frequency defined by this register. The relationship between
the duration period of each tone and the 8 bit warble coefficient is as follows:
Tone duration (warble frequency) = 500 / COEF
where: Frequency is in Hz, and 0
