2.1.13 Automatic Cascading Detection (ACD)
The TLV320AIC11’s ACD makes cascade programming easy and supports the operation of up to eight devices in
cascade. See Appendix A for register map description.

2.1.14 Low-Power Mode
To select the low-power mode, in which the AIC11 typically consumes 39 mW, set bit D7 of control register 2 to 1 and
set the sampling rate at 8 ksps.
2.1.15 Event-Monitor Mode
This mode, which is only available during the register-write cycle, is enabled by writing 11 to bits D6 and D7 of control
register 3. The event monitor mode is provided for applications that need hardware control and monitoring of external
events. By allowing the device to drive the FLAG terminal (set through bit D3 of the control register 3), the host DSP
is capable of system control through the same serial port that connects the device. Along with this control is the
capability of monitoring the value of the ALTIN terminal during a secondary communication cycle. One application
of this function is in monitoring RING DETECT or OFFHOOK DETECT from a phone-answering system. FLAG allows
response to these incoming control signals. Figure 2–7 shows the timing associated with this operating mode.
