Data Sheet
In order to ease programming the DSP automatically increments the address ADR after
each access to FCFCOF1 or FCFCOF2 respectively.
Note: Any access to an out-of-range address automatically resets FCFCTL1:ADR.
20.1.12
The DSP contains an universal tone generator which can be used for tone alerting, call
progress tones or other audible feedback tones. Figure 20-26 shows a block diagram of
this unit.

The heart of this unit are the four independent sine/square wave generators that can
generate individually programmable frequencies (F
associated amplifier (G
controlled by the beat generator.
If the beat generator is enabled, then the output is either a three tone cadence or a two
tone cadence as shown in Figure 20-27.
