Description
A RW CRCPOLY CRC polynomial
Each term in the CRC polynomial is mapped to a bit in this
register which index corresponds to the term's exponent. The
least significant term/bit is hard-wired internally to 1, and bit
number 0 of the register content is ignored by the hardware.
The following example is for an 8 bit CRC polynomial: x8 + x7 +
x3 + x2 + 1 = 1 1000 1101 .

A RW TIFS Inter Frame Spacing in us
Inter frame space is the time interval between two consecutive
packets. It is defined as the time, in micro seconds, from the
end of the last bit of the previous packet to the start of the first
bit of the subsequent packet.
