CMX808A Preliminary Information
5.5 Rx Tone Table
The following table lists the commonly used CTCSS tones together with the values for programming the
CTCSS RX PROGRAM register $84 for tone address 0. (Tone addresses 1 to 6 are also available.) Other
tones within the supported tone range can also be configured as described in Section 4.1.2.5.
NOTE: The most significant nibble (four bits) of Byte 1 determines the tone register address being configured
and is independent of the configured tone frequency. For example, this nibble (left hex character of Byte 1) is
set to $0 (hex), corresponding to tone address 0, for all entries in the table below. As another example the
same tone table for tone address 5 would require this nibble to be set to $5 (hex) for all values in the table
e.g. 67.0Hz would be $53 (Byte 1) $DC (Byte 2).
