3.5 CRC Checksum Computation

Unlike older PIC^® devices, the Microchip toolchain runs a 32-bit CRC calculation on the entire hex file to calculate its checksum. The checksum uses the standard CRC-32 algorithm with the polynomial 0x4C11DB7 $(x^{32}+x^{26}+x^{23}+x^{22}+x^{16}+x^{12}+x^{11}+x^{10}+x^8+x^7+x^5+x^4+x^2+x+1)$.
