These registers define the system memory base address for the receive FIFO if the FIFO address mode bit
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.
22.5.2.52 Receive FIFO Periodic Timer Register (RFPTR)
This register holds periodic timer duration for the periodic FIFO timer. The periodic timer applies to both
FIFOs (see
Section 22.6.9.3, FIFO Periodic Timer
).

Periodic Timer Duration — This value defines the periodic timer duration in terms of macroticks.
0000 timer stays expired
3FFF timer never expires
other timer expires after specified number of macroticks, expires and is restarted at each cycle start
