Delta Loop Current Sense Interrupt
0 = The LCS bits have not changed value.
1 = The LCS bits have changed value; a hardware interrupt occurs on the AOUT/INT pin. This bit
must be written to a 0 to be cleared.
Polarity Reversal Detect Interrupt.
0 = Bit 7 of the LVS register does not change states.
1 = Bit 7 of the LVS register changes from a 0 to a 1, or from a 1 to a 0, indicating the polarity of
TIP and RING is switched. If the POLM and INTE bits are set, a hardware interrupt occurs on the
AOUT/INT pin. To clear the interrupt, write this bit to 0.
Ring Detect Signal Negative.
0 = No negative ring signal is occurring.
1 = A negative ring signal is occurring.
Ring Detect Signal Positive.
0 = No positive ring signal is occurring.
1 = A positive ring signal is occurring.
Off-hook Polarity.
0 = Off-hook pin is active low.
1 = Off-hook pin is active high.
On-Hook Line Monitor.
0 = Normal on-hook mode.
1 = Enables low-power on-hook monitoring mode allowing the host to receive line activity
without going off-hook. This mode is used for caller-ID detection.
Ring Detect.
0 = Reset either 5 seconds after last positive ring is detected or when the system executes an
off-hook. Only a positive ring sets this bit when RFWE = 0. When RFWE = 1, either a positive
or negative ring sets this bit.
1 = Indicates a ring is occurring.
Off-hook Pin Enable.
0 = Off-hook pin is ignored.
1 = Enables operation of the off-hook pin.
Off-Hook.
0 = Line-side device on-hook.
1 = Causes the line-side device to go off-hook. This bit operates independently of the OHE bit
and is a logic OR with the off-hook pin when enabled.
