-/* 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: */
-/* */
-/* 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. */
-/* */
-/* 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. */

+/* 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: */
+/* */
+/* 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. */
+/* */
+/* 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 */
