PIN4_MODE
R/W
Pin 4 mode select, set this bit to 1 will enable PWMOUT2 output, else
if set this bit to 0, pin 4 will be enable the GPIO1 function.(default)
This mode is trappable: When PIN3 trapped to high at power-on,
PIN4 is set to PWMOUT2. When PIN3 trapped to low at power-on,
PIN4 is set to GPIO1.
0
PIN2_MODE
R/W
Pin 2 mode select, set this bit to 1 will enable FANIN2 input, if set this
bit to 0 pin 2 will be enable the GPIO0 function.(default).
This mode is trappable: When PIN3 trapped to high at power-on,
PIN2 is set to FANIN2. When PIN3 trapped to low at power-on, PIN2
is set to GPIO0.

01: pin5 is used as SMI
10: pin5 is used as Fan fault function
11: LED out(1Hz/0.5Hz select by bit2)
If set to 0, SMI will be level mode else if this bit set to 1, SMI will be
pulse mode.
