CLKOUT Output Divider.
Sets value for CLKOUT output divider. Allowed values are [1] and [2, 4, 6, ..., 2
gal odd divider values will be rounded up to the nearest even value. The value for the
N1 register can be calculated by taking the divider ratio minus one. For example, to
divide by 10, write 0001001 (9 decimal) to the N1 registers.
0000000 = 1
1111111 = 2
