and off-hook.
These registers can help determine the following:
When on-hook, detect if a line is connected.
When on-hook, detect if a parallel phone is off-hook.
When off-hook, detect if a parallel phone goes on or
off-hook.
Detect if enough loop current is available to operate.
When used in conjunction with the OPD bit, detect if
an overload condition exists (See "6.25. Overload
6.11.1. Line Voltage Measurement (Si3062, Si3063,
and Si3065 Only)
The Si3062, Si3063, and Si3065 devices report line
voltage with the LVS[7:0] bits (Register 29) in both on-
and off-hook states with a resolution of 1 V per bit. The
accuracy of these bits is approximately ±10%. Bits 0
through 6 of this register indicate the value of the line
voltage in 2s compliment format. Bit 7 of this register
indicates the polarity of the tip/ring voltage.
If the INTE bit (Register 2) and the POLM bit (Register
3) are set, a hardware interrupt is generated on the
AOUT/INT pin when bit 7 of the LVS register changes
state. The edge-triggered interrupt is cleared by writing
0 to the POLI bit (Register 4). The POLI bit is set each
time bit 7 of the LVS register changes state and must be
written to 0 to clear it.
The default state of the LVS register forces the LVS bits
to 0 when the line voltage is 3 V or less. The LVFD bit
(Register 31, bit 0) disables the force-to-zero function
and allows the LVS register to display non-zero values
of 3 V and below. This register might display
unpredictable values at line voltages between 0 to 2 V.
At 0 V, the LVS register displays all 0s.
6.11.2. Loop Current Measurement
When the DAA is off-hook, the LCS[4:0] bits measure
loop current in 3.3 mA/bit resolution. These bits enable
detection of another phone going off-hook by monitoring
the dc loop current. The line current sense transfer
The LCS and LCS2 bits report loop current down to the
minimum operating loop current for the DAA. Below this
threshold, the reported value of loop current is
unpredictable.
