DESCRIPTION

R/W
0101 1101
Fan filter register:
Bit 7: Fan spin-up disable:
0: Spin-up enabled; 1: spin-up disabled.
Bits [6:5]: Fan ramp rate: These bits set the amount the PWM duty cycle can change
on each monitoring cycle:
00 = 1 (0.416%)
01 = 2 (0.833%)
10 = 4 (1.667%) (default)
11 = 8 (3.333%)
Bits [4:2]: Temperature measurement rate (see Table 5).
Bit 1: Unused.
Bit 0: Fan filter enable. Setting the bit to 1 enables the fan filter function.
