22. Calling Party Control (CPC)
In some countries, after the called party is on hook, a pulse is sent to the caller party by stopping the line current
of the caller party for a short time to indicate that the called party is on hook, as seen in Figure 22-1. The duration
of this pulse varies widely for different countries. The purpose of having Calling Party Control (CPC) circuit is to
detect the on-hook signal by sampling CPC signal.

Figure 22-1: CPC Signal
Firmware Note:
In order to setup CPC circuit, the following initialization procedure must be done in the given
order after both parties are off hook:
1. Write the desired threshold in CPCThreshold register
2. Select the sampling period in CPCStatCtrl register (This will clear the CPCflag and reset CPC
counter to zero)
Once CPC has been set up, the firmware can periodically check CPCflag by reading
CPCStatCtrl register.
