+ code or tables extracted from it, as desired without restriction.*/
+
+ /* First, the polynomial itself and its table of feedback terms. The */
+ /* polynomial is */
+ /* X^32+X^26+X^23+X^22+X^16+X^12+X^11+X^10+X^8+X^7+X^5+X^4+X^2+X^1+X^0 */
+ /* Note that we take it "backwards" and put the highest-order term in */
+ /* the lowest-order bit. The X^32 term is "implied"; the LSB is the */
+ /* X^31 term, etc. The X^0 term (usually shown as "+1") results in */
+ /* the MSB being 1. */
+
+ /* Note that the usual hardware shift register implementation, which */
+ /* is what we're using (we're merely optimizing it by doing eight-bit */
+ /* chunks at a time) shifts bits into the lowest-order term. In our */
+ /* implementation, that means shifting towards the right. Why do we */
+ /* do it this way? Because the calculated CRC must be transmitted in */
+ /* order from highest-order term to lowest-order term. UARTs transmit */
+ /* characters in order from LSB to MSB. By storing the CRC this way, */
+ /* we hand it to the UART in the order low-byte to high-byte; the UART */
+ /* sends each low-bit to hight-bit; and the result is transmission bit */
+ /* by bit from highest- to lowest-order term without requiring any bit */
+ /* shuffling on our part. Reception works similarly. */
+
+ /* The feedback terms table consists of 256, 32-bit entries. Notes: */
+ /* */
+ /* 1. The table can be generated at runtime if desired; code to do so */
+ /* is shown later. It might not be obvious, but the feedback */
+ /* terms simply represent the results of eight shift/xor opera- */
+ /* tions for all combinations of data and CRC register values. */
+ /* */
+ /* 2. The CRC accumulation logic is the same for all CRC polynomials, */
+ /* be they sixteen or thirty-two bits wide. You simply choose the */
+ /* appropriate table. Alternatively, because the table can be */
+ /* generated at runtime, you can start by generating the table for */
+ /* the polynomial in question and use exactly the same "updcrc", */
+ /* if your application needn't simultaneously handle two CRC */
+ /* polynomials. (Note, however, that XMODEM is strange.) */
+ /* */
+ /* 3. For 16-bit CRCs, the table entries need be only 16 bits wide; */
+ /* of course, 32-bit entries work OK if the high 16 bits are zero. */
+ /* */
+ /* 4. The values must be right-shifted by eight bits by the "updcrc" */
+ /* logic; the shift must be unsigned (bring in zeroes). On some */
+ /* hardware you could probably optimize the shift in assembler by */
+ /* using byte-swap instructions. */
