Special tones 1-4 provide user programmable tone options for both transmit and receive modes
as set in the indicated Program register, for programming information see section 1.6.20.2.
Normal tone 14 is the repeat tone, this code must be used in transmit when the new code to be
sent is the same as the previous one. e.g. to send ‘333’ the sequence ‘3R3’ should be sent,
where ‘R’ is the repeat tone. When receiving Selcall tones the CMX882 will indicate the repeat
tone when it is received, it is up to the host to interpret this and decode tones accordingly.
