Charge Pump Disable.
This bit disables the internal charge pump when set.
Receive Overload.
This bit is set when the receive input detects an excessive input level. A write of zero is
required to clear this bit. (This bit is disabled when BTE = 0 in Register 5Ch.)
Billing Tone Detected.
This bit will be set if BTE bit of register 5Ch is enabled and a billing tone is detected. A
write of zero is required to clear this bit. (This bit is only active when BTE = 1 in
Register 5Ch.)

high, it remains high until a logic 0 is written to it.
Frame Detect.
0 = Indicates ISOcap communication has not established frame lock.
1 = Indicates ISOcap frame lock has been established.
Loop Current Sense.
Four-bit value returning the loop current in 6 mA increments.
0 = Loop current < 0.4 mA typical
1111 = Loop current > 155 mA typical. See "Loop Current Monitor" on page 28.
Ring Detect Signal Positive.
1 = Positive ring signal is occurring.
Ring Detect Signal Negative.
1 = Negative ring signal is occurring.
1 = Indicates a communication problem between the Si3024 and Si3014. When it goes
