Figure 26-54. Receive FIFO System Memory Base Address Low Register (FR_RFSYMBADLR)
These registers define the system memory base address for the receive FIFO if the FIFO address mode bit
FR_MCR[FAM] is set to 1. The system memory base address is used by the BMIF to calculate the physical
memory address for system memory accesses for the FIFOs.

Description
System Memory Base Address — This is the value of the system memory base address for the
receive FIFO if the FIFO address mode bit FR_MCR[FAM] is set to 1. It is defines as a byte address.

Figure 26-55. Receive FIFO Periodic Timer Register (FR_RFPTR)
This register holds periodic timer duration for the periodic FIFO timer. The periodic timer applies to both
FIFOs (see Section 26.6.9.3, FIFO Periodic Timer).
