4.0 Registers
4.1 Registers
0x41—RXCELLINT (Receive Cell Interrupt Indication Status Register)
The RXCELLINT register indicates that a change of status has occurred within its affiliated status signals.
0x66—RXCNTH (Received Cell Counter [High Byte])
The RXCNTH counter tracks the number of received cells.

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.
