I wanted to ask what are the equations used to generate the PN9 and PN23 sequence of the ADC test patterns.
In the manual, it is said that the first values are:
PN9: 0x0092 -- 0x125B, 0x3C9A, 0x2660, 0x0c65, 0x0697
PN23: 0x3AFF -- 0x3FD7, 0x0002, 0x26E0, 0x0A3D, 0x1CA6
But I am unable to generate those using the typical LFSR shifted by one and X-ored. I believe there is a more complex equation behind, right?
