-Payload data must be XOR’ed into the LSB end of the state before executing the CRC instruction. The following code demonstrates the use of crc32.b:
-uint32_t crc32_demo(const uint8_t *p, int len) { uint32_t x = 0xffffffff;
-for (int i = 0; i < len; i++) { x = x ^ p[i];
-x = crc32_b(x); } }return ~x;
