PWM Input Clock Select. This bit select Fan 1 input
clock to pre-scale divider.
0: 24 MHz
1: 180 KHz
Fan 1 Input Clock Pre-Scale. The divider of input
clock is the number defined by pre-scale. Thus, writing
1 transfers the input clock directly to counter. The
maximum divider is 128 (7Fh).
01h : divider is 1
02h : divider is 2
03h : divider is 3
