Read/Write
PWM Input Clock Select. This bit select Fan 1 input
clock to pre-scale divider.

PRE_SCALE1[6:0]
Read/Write
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
PWM frequency = (Input Clock / Pre-scale) / 256
