Respective bit(s) are set to “1” every time the LOS processor detects a valid loss of
signal condition in transceivers 7–0. RCLK is used as timing reference. If RCLK is not
available an internal timing signal is used to qualify the LOS condition. Any change in
the state causes an interrupt. On power up the register is set to “0.” All LOS interrupts
are cleared by a single read operation.
Respective bit(s) are set to “1” every time the short circuit monitor detects a valid
secondary output driver short circuit condition in transceivers 7–0. On power-up all the
register bits are set to “0.” All DFM interrupts are cleared by a single read operation.
Transceiver 7–0 LOS interrupts are enabled by writing a “1” to the respective bit. On
power-up all the register bits are set to “0”and all interrupts are disabled.
Transceiver 7–0 DFM interrupts are enabled by writing a “1” to the respective bit. On
power-up all the register bits are set to “0”and all interrupts are disabled.
These bits are set to “1” every time a LOS status change has occurred since the last
cleared interrupt in transceivers 7–0 respectively.
These bits are set to “1” every time a DFM status change has occurred since the last
cleared interrupt in transceivers 7–0 respectively.
Setting a bit to “1” resets the respective transceiver 7–0 respectively. This does not
reset the register (‘0’ clears the reset).
