TX Register Description
The following tables describe the registers for the transmitter section of
the PP155
.
RX_PM_RUNT - Receive Runt Frame Count - ’h0C
Field
Bits
Access
Function
Default
CNT
15:0
RTCW
Count of runt frames.
Runt packets are packets received with frames shorter than
3 or 5 octets (depending on the setting of crclen), not
including stuff octets and flags. Individual runt packets
increment the count. The counter saturates at 0xFFFF and
does not wrap to 0. Reading this register clears the count.
32-bit values may be written to this register for testing.
0
TX_CTRL - Transmit Control Register - ’h10
Field
Bits
Access
Function
Default
CRCLEN
2
RW
Set to 1 for CRC-32 (32 bits); 0 for CRC-CCITT (16 bits).
If set, the transmit section computes FCSs for transmit
packets using the CRC-32 polynomial; if cleared, the CRC-
CCITT 16-bit polynomial is used. The FCS is always
generated and appended.
0
SCRAMEN
1
RW
Enables scrambling of the transmit frame.
This causes the transmitted data stream to be scrambled
using the x^43+1 scrambling polynomial. The bits are
scrambled using the most significant (higher-numbered) bit
first. All bits, including flags, the body of the packet, and the
FCS are scrambled.
