2.2.4. Loop Voltage and Current Monitoring
The ProSLIC continuously monitors the TIP and RING
voltages and external BJT currents. These values are
available in registers 78–89. Table 22 lists the values
that are measured and their associated registers. An
internal A/D converter samples the measured voltages
and currents from the analog sense circuitry and
translates them into the digital domain. The A/D updates
the samples at an 800 Hz rate.
