73 TST17
I
Test Pin
This pin must be open.
74 TST18
I
Test Pin
This pin must be open.
75 VSS1
- Ground Pin, 0V
76 AVDD1
- Analog Power Supply Pin, 3.0V∼3.6V
77 VREFH1
I Positive Voltage Reference Input Pin, AVDD1
78 VCOM
O
Common Voltage Output Pin, AVDD1x1/2
Large external capacitor around 2.2µF is used to reduce power-supply noise.
79 TST19
I
Test Pin
This pin must be open.
80 TST20
I
Test Pin
This pin must be open.
Note 1. This pin becomes OVF pin when OVFE bit is set to “1”.
Note 2. This pin becomes DZF pin when OVFE bit is set to “0”.
Note 3. This pin becomes analog negative input pin in differential input mode, and becomes output pin invert the positive
input pin in single-end input mode. This pin must be open in single-end input mode.
Note 4. All digital input pins except for pull-down must not be left floating.
