* RLS6 is reserved for future use.
** Currently, RLS2 does not create an interrupt, therefore this bit is not used in T1 mode.
The Receive Interrupt Information register (RIIR) indicates which of the DS26528 status registers are generating an
interrupt. When an interrupt occurs, the host can read RIIR to quickly identify which of the receive status registers
is (are) causing the interrupt(s). The RIIR bits clear once the appropriate interrupt has been serviced and cleared,
as long as no additional, unmasked interrupt condition is present in the associated status register. Status bits that
have been masked via the Receive Interrupt Mask (RIMx) registers will also be masked from the RIIR register.
