4.0 Registers
4.1 Registers
0x3E—LININT (Receive Line Interrupt Indication Status Register)
The LININT register indicates that a change of status has occurred within its affiliated status signals.
0x4C—LOCDCNT (LOCD Event Counter)
The LOCDCNT counter tracks the number of LOCD events.
4-32

Dual event—Either a 0 –> 1 or a 1 –> 0 transition on the corresponding status bit causes this interrupt to occur provided that
this interrupt has been enabled by the corresponding enable bit. Reading the interrupt register clears the interrupt.
Single event—A 0 –> 1 transition on the corresponding status bit causes this interrupt to occur provided that this interrupt has
been enabled by the corresponding enable bit. Reading the interrupt register clears the interrupt.
