6.4.1 PCIe Reset CSR Configuration Section Length - Offset 0x0
The section length word contains the length of the section in words. Note that section length count does
not include the section length word and Block CRC8 word.
6.4.2 Block CRC8 (Offset 0x1)
6.4.3 CSR Address - (Offset 3*n - 1; [n = 1... Section Length])
6.4.4 CSR Data LSB - (Offset 3*n; [n = 1... Section Length])
