automatically adjusted according to FAN2 EXPECT register.
01: FAN2 operates in TEMPERATURE mode. PWMOUT2 duty-cycle
is automatically adjusted according to FAN2 EXPECT register, which
will be automatically loaded into preset values according to the
current temperature. (When PIN3 power-on trapped to 1, this mode
is selected after power-on.)
1X: FAN2 operates in MANUAL mode. Software set the PWMOUT2
duty-cycle directly.

Set to 1, enable interface_idle timer. Set to 0, disable the timer.
When the timer is enabled, if software doesn’t access the this chip
through GP_CLK and GP_DATA, the reset timer starts to count down
according to the value set in INDEX 62H. When it counts down to
zero, INDEX[72H, 73H] will be loaded into INDEX[74H,75H].
