The Receive FIFO Full interrupt will be generated once all free space in the buffer is used or all TLB slots are filled.
The host processor should read the RXFIFOSTA register to determine the cause of the interrupt. To receive
additional packets after the buffer is filled, packets must be removed from the buffer by reading them out or
discarding them. Packets can be discarded one at a time or all at once by writing ‘1’ to RXCLEAR (RXCN.0).
12.7. Receive Buffer Advanced Status and Control Registers
The receive buffer is controlled and managed through the registers in Table 17. These registers are not commonly
accessed by the host processor except for debug purposes.

Description
CPTLB
Current Packet TLB Number
0x1A
Specifies the TLB number (0–7) associated with
the current packet.
TLBVALID
TLB Valid Indicator
0x1C
Indicates which TLBs currently have valid pack-
ets.
TLBnINFOH
TLBnINFOL
TLBn Packet Information
multiple
Specifies information about the packet associ-
ated with TLBn (n = 0–7).
TLBLENH
TLBLENL
TLBn Packet Length
multiple
Specifies the length of the packet associated
with TLBn (n = 0–7).
TLBnADDRH
TLBnADDRL
TLBn Packet Address
multiple
Specifies the starting address of the packet
associated with TLBn (n = 0–7).
RXFIFOTAILH
RXFIFOTAILL
Receive FIFO Buffer Tail Pointer
0x15
0x16
Points to the byte following the last valid byte.
This is where new packets are added.
RXFIFOHEADH
RXFIFOHEADL
Receive FIFO Buffer Head
Pointer
0x17
0x18
Points to the beginning of the current packet
and is incremented with each Auto Read.
RXFIFOSTA
Receive FIFO Buffer Status
0x5B
Indicates the cause of the Receive FIFO Buffer
Full interrupt.
Bits 7–3: UNUSED. Read = 00000b; Write = don’t care.
Bits 2–0: CPTLB[2:0]: Current Packet TLB Number
The TLB Number (0–7) of the TLB slot associated with the current packet.
