An active low standard ISA bus I/O Read Control.
An active low standard ISA bus I/O Write Control.
System clock input. Can select 48MHz or 24MHz or
14.318MHz. The default is 24MHz.
Bi-directional ISA bus Data lines. D0 corresponds to the
low order bit, with D7 the high order bit. These pins are
activated if pin ADRMSEL=0.
Bi-directional ISA bus Data lines. This pin is activated if
pin ADRMSEL=0.
Fan speed control PWM output. This pin is activated if
pin ADRMSEL=1.
Bi-directional ISA bus Data lines. This pin is activated if
pin ADRMSEL=0.
Fan speed control PWM output. This pin is activated if
pin ADRMSEL=1.
Voltage Supply readouts from P6. This value is read in
the VID/Fan Divisor Register.

10μF (electrolytic or tantalum) and 0.1μF (ceramic)
bypass capacitors.
Internally connected to all digital circuitry.
Master reset input.
CASE OPEN detection. An active low input from an
external device when case is opened. This signal can
be latched if pin VBAT is connect to battery, even
W83782D/G is power off.
Voltage Supply readouts from P6. This value is read in
the bit <0> of Device ID Register.
