5.3.6
The transmit line monitor compares the transmit line pulses on XL1 and XL2 with the
transmit input signals received on pins XL1M and XL2M. The monitor detects faults on
the primary side of the transformer and protects the device from damage by setting the
transmit lines into high impedance state automatically. Faults on the secondary side can
not be detected. To detect shorts, the configuration shown in
provided and the default (reset) value of registers XPM0...2 must be selected. Otherwise
a short detection can not be guaranteed. Two conditions are detected by the monitor:
“Transmit Line Ones Density“ (more than 31 consecutive zeroes) and “Transmit Line
Shorted“. In both cases a transmit line monitor status change interrupt is provided.
