33.5.2.54 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 33.6.9.3, FIFO periodic timer ”).
33.5.2.55 Receive FIFO Watermark and Selection Register (FR_RFWMSR)
This register is used to
• select a receiver FIFO for subsequent programming access through the receiver FIFO
configuration registers summarized in
Table 33-63 .
• to define the watermark for the selected FIFO.

Field Description
PTD 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
