Clock Addend (CLOCK_ADDEND)
This 32-bit value is added to the 1588 frequency divisor accumulator every
cycle. This allows the base 100MHz frequency of the 64-bit 1588 Clock to
be adjusted accordingly.
1588 Clock Addend Register (1588_CLOCK_ADDEND)
This read/write register is responsible for adjusting the 64-bit 1588 Clock frequency. Refer to
Chapter 11, "IEEE 1588 Hardware Time Stamp Unit," on page 155
