23.1
The module implements a software configurable CRC
generator. The terms of the polynomial and its length
can be programmed using the CRCXOR
(X<15:1>) and the CRCCON bits (PLEN<3:0>),
respectively.
EQUATION 23-1:
To program this polynomial into the CRC generator,
the CRC register bits should be set as shown in
Table
TABLE 23-1:
For the value of X<15:1>, the 12th bit and the 5th bit are
set to ‘1’, as required by the CRC equation. The 0th bit
required by the CRC equation is always XORed. For a
16-bit polynomial, the 16th bit is also always assumed
to be XORed; therefore, the X<15:1> bits do not have
the 0th bit or the 16th bit.
The topology of a standard CRC generator is shown in
