Clock Conversion

Register Bank 0
This register must be set according to the CLK (Clock) input frequency.
All timings longer than 400 ns depend on this register correctly agreeing
with the CLK frequency. The clock conversion factor is equal to the
binary encoded version of the least significant three bits. It should be set
to one of the seven values shown in
Table 4.7
These bits must never be loaded with a binary 0b001. Hardware Reset
or the Reset command sets the Clock Conversion Factor to a binary
0b010. The upper five bits of this register are reserved.
