5.2.3 TX Tone Generator Registers 1 and 2
Each TX Tone Generator is controlled individually by writing a two-byte command to the relevant TX Tone Generator
Register. The format of this command word, which is different for each tone generator, is shown below with the
calculations required for tone frequency (f
TONE
) generation described in the following text.

These 13 bits (0 to 12) are used to produce a binary number,
designated ‘A’. ‘A’ is used in the formulas below to set the TX
Tone 1 frequency (f

Write to TX Tone Generator 2 Register Notes:
Programming Tone Generator 2 to Notone will place the CAL/CUES output at V
BIAS
via a 40k
internal resistor.
Programming Tone Generator 2 to Powersave will place the CAL/CUES output at V
