Description
of JP6 (pin 2). (2.0/0.8V when JP6=1, 0.8/0.4V when
JP6=0)
• The second function of this pin is the General
Purpose I/O 33.
• The function configuration of this pin is decided by the
software configuration registers.
Voltage ID 4 / General Purpose I/O 34.
• The first function of this pin is Voltage ID Input 4. The
Voltage ID is the voltage supply readouts from the
CPU. This value is read in the VID register. The input
threshold can be selected by the power-on strapping
of JP6 (pin 2). (2.0/0.8V when JP6=1, 0.8/0.4V when
JP6=0)
• The second function of this pin is the General
Purpose I/O 34.
• The function configuration of this pin is decided by the
software configuration registers.
Voltage ID 5 / General Purpose I/O 35.
• The first function of this pin is Voltage ID Input 5. The
Voltage ID is the voltage supply readouts from the
CPU. This value is read in the VID register. The input
threshold can be selected by the power-on strapping
of JP6 (pin 2). (2.0/0.8V when JP6=1, 0.8/0.4V when
JP6=0)
• The second function of this pin is the General
Purpose I/O 35.
• The function configuration of this pin is decided by the
software configuration registers.
Case Open Detection #.
• The Case Open Detection is connected to a specially
designed low power CMOS flip-flop backed by the
battery for case open state preservation during power
loss.

Description
Fan Control Output 1.
(PWM output signal to Fan’s FET.)
Fan Control Output 2 / General Purpose I/O 51.
• The first function of this pin is Fan Control Output 2.
(PWM output signal to Fan’s FET.)
• The second function of this pin is the General
Purpose I/O Port 5 Bit 1.
• The function configuration of this pin is determined by
programming the software configuration registers.
Fan Control Output 3 / General Purpose I/O 36.
• The first function of this pin is Fan Control Output 3.
(PWM output signal to Fan’s FET.)
• The second function of this pin is the General
Purpose I/O Port 3 Bit 6.
• The function configuration of this pin is determined by
programming the software configuration registers.
