Si1010/1/2/3/4/5
15. Cyclic Redundancy Check Unit (CRC0)
Si1010/1/2/3/4/5 devices include a cyclic redundancy check unit (CRC0) that can perform a CRC using a
16-bit or 32-bit polynomial. CRC0 accepts a stream of 8-bit data written to the CRC0IN register. CRC0
posts the 16-bit or 32-bit result to an internal register. The internal result register may be accessed indi-
rectly using the CRC0PNT bits and CRC0DAT register, as shown in Figure 15.1. CRC0 also has a bit
reverse register for quick data manipulation.
15.1. CRC Algorithm
The Si1010/1/2/3/4/5 CRC unit generates a CRC result equivalent to the following algorithm:
1. XOR the input with the most-significant bits of the current CRC result. If this is the first iteration of the
2. If the MSB of the CRC result is set, shift the CRC result and XOR the result with the selected
3. If the MSB of the CRC result is not set, shift the CRC result.
The algorithm is also described in the following example.
