00: pin5 function is GPIO2
01: pin5 is used as SMI
10: pin5 is used as Fan fault function
11: LED out(1Hz/0.5Hz select by bit2)
This mode is trappable: When PIN3 trapped to high at power-on,
PIN5 is set to Fan fault function. When PIN3 trapped to low at
power-on, PIN5 is set to GPIO2.
If set to 0, SMI will be level mode else if this bit set to 1, SMI will be
pulse mode.
When set this bit to 0 SMI is low active (default). if set to 1 SMI is high
active
When set this bit to 1 fan fault LED output frequency will be 0.5HZ,
else is 1Hz(default)

Set to 1, select VT2 as connected to a BJT. Set to 0, select
VT2 as connected to a thermistor. (Default is 0)
Set to 1, select VT1 as connected to a BJT. Set to 0, select
VT1 as connected to a thermistor. (Default is 0)
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.
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.
