6 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.

Example CRC Checksum Computation

(x32 + x26 + x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1)
