The programmable CRC generator offers the following
features:
• User-programmable polynomial CRC equation
• Interrupt output
• Data FIFO
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>) bits
and the CRCCON (PLEN3:PLEN0) bits, respectively.

Consider the CRC equation:
To program this polynomial into the CRC generator,
the CRC register bits should be set as shown in
Table 20-1.
TABLE 20-1:
Note that for the value of X<15:1>, the 12th bit and the
5th bit are set to ‘1’, as required by the equation. The 0
bit required by the 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 0 bit or the 16th bit.
The topology of a standard CRC generator is shown in
Figure 20-2.
