9.5.5 Receive Serial Interface
Serial Receive Registers are used to control the HDLC Receiver associated with each Serial Interface. Note that
throughout this document HDLC Processor is also referred to as “Packet Processor”. The receive packet
processor block has seventeen registers.

Bit 0: Receive Data Enable Polarity (RDENPLT) Receive Data Enable Polarity. If set to 1, RDEN Low enables
reception of the bit.

Bit 5: Receive FCS Processing Disable (RFPD) – When equal to 0, FCS processing is performed and FCS is
appended to packets. When set to 1, FCS processing is disabled (the packets do not have an FCS appended). In
X.86 mode, FCS processing is always enabled.
Bit 4: Receive FCS-16 Enable (RF16) – When 0, the error checking circuit uses a 32-bit FCS. When 1, the error
checking circuit uses a 16-bit FCS. This bit is ignored when FCS processing is disabled. In X.86 mode, the FCS
is always 32 bits.
Bit 3: Receive FCS Extraction Disable (RFED) – When 0, the FCS bytes are discarded. When 1, the FCS bytes
are passed on. This bit is ignored when FCS processing is disabled. In X.86 mode, FCS bytes are discarded.
Bit 2: Receive Descrambling Disable (RDD) – When equal to 0, X
43+1 descrambling is performed. When set to
1, descrambling is disabled.
Bit 1: Receive Bit Reordering Enable (RBRE) – When equal to 0, reordering is disabled and the first bit
received is expected to be the MSB DT [7] of the byte. When set to 1, bit reordering is enabled and the first bit
received is expected to be the LSB DT [0] of the byte. Note that function is controlled by the BREO in Hardware
Mode.
Bit 0: Receive Clear Channel Enable (RCCE) – When equal to 0, packet processing is enabled. When set to 1,
the device is in clear channel mode and all packet-processing functions except descrambling and bit reordering
are disabled.
