PWM Input Clock Select. This bit select Fan input clock
to pre-scale divider.
0: 14.318MHz(External)
Fan PWMOUT Input Clock Pre-Scale. The divider of
input clock is the number defined by pre-scale. Thus,
writing 0 transfers the input clock directly to counter. The
maximum divider is 128 (7Fh).
00h : divider is 1
01h : divider is 2
02h : divider is 3
