8-bit LFSR

8-bit Fibonacci-type Linear Feedback Shift Register (LFSR). The polynomial x^8+x^6+x^5+x^4+1 defines the feedback taps. The register generates a pseudo-random sequence of 255 distinct values.

The i_load signal loads an initial value. Reset is synchronous and active-high (initial value: 0x01).

• Polynomial: x^8+x^6+x^5+x^4+1 (taps: bits 7, 5, 4, 3)
• Rising-edge priority: reset > load > enable
• Reset value: 0x01
