Generate tone ringer
Description
Program Initialization steps above except A-Law vs -Law choices are not required.
set speaker gain (ie -12dB)
write low tone coefficient
write high tone coefficient
select ringer as source for loudspeaker
start tone ringer (warble = 5Hz)
or (warble = 10Hz)
control ringer cadence by toggling
Ring EN (ie warble = 10Hz)
Generate DTMF tones transmit only
Description
Program Initialization steps above
set Tx digital gain (ie 0 dB)
(-4dBm0/ -Law,-10dBm0/A-Law)
write low tone coefficient

select receive path
or (ie Rx Filter to handsfree speaker)
or (ie Rx Filter to AUX out)
start DTMF program with sidetone
or for single tones
DTMF transmit and sidetone
