L601 CRC Division Example

Isnt the CRC / Polynomial Value 0x25 6 Bits long, yet it says "5-Bit CRC.." ? Anyways, super helpful video, thanks!👍

It computes a 5-bit check value, which requires a 6 bit polynomial to specify in full notation. People generally refer to the CRC size as the size of the check value, and the full representation of the polynomial is +1 bits in size. (For example, a 32-bit CRC has 33 bits in its polynomial including the x**32 term and the +1 term.)

@@philkoopman ah okay that makes sense! Thanks for clarifying :)
