General Functions and Device Architecture T1
Transmit Line Monitor
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 line driver XL1/2 automatically in a high impedance state. Faults on the
secondary side may not be detected. To detect a short the configuration in figure 47 and
the reset values of register XPM0-2 has to be fulfilled. Otherwise the short detection
could not be guaranteed. Two conditions will be detected by the monitor: Transmit Line
ones density (more than 31 consecutive zeros) and Transmit Line Shorted. In both cases
a transmit line monitor status change interrupt will be provided.
