The SCLK frequency is set by the frequency of MCLK. There is a 2-stage clock divider that sets the SCLK
frequency as MCLK/4.

Phone mode control is provided for applications that need hardware control and monitoring of external
events. By allowing the device to drive two FLAG terminals (set through the Control 2 register), the host
(DSP) is capable of system control through the same serial port that connects to the device. Along with this
control is the capability of monitoring the value of the ALT DATA terminal during a secondary communication
cycle. One application for this function is in monitoring RING DETECT or OFFHOOK DETECT from a phone
answering system. The two FLAG terminals allow response to these incoming control signals. Figure 3–6
shows the timing associated with this operating mode.
