V
LCD1
LCD Bias, Voltage 1.
LCD drive voltage used with 1/2 and 1/3 LCD bias. An internal resistor-
divider sets the voltage. External resistors and capacitors can be used to change the LCD voltage
or drive capability at this pin.
47
56
V
LCD2
LCD Bias, Voltage 2.
LCD drive voltage used with 1/3 LCD bias. An internal resistor-divider sets
the voltage. External resistors and capacitors can be used to change LCD voltage or drive
capability at this pin.
48
57
V
ADJ
LCD Adjustment Voltage.
Connect to an external resistor to provide external control of the LCD
contrast. Leave disconnected for internal contrast adjustment.

RESET
Digital, Active-Low, Reset Input/Output.
The CPU is held in reset when this is low and begins
executing from the reset vector when released. The pin includes pullup current source and should
be driven by an open-drain, external source capable of sinking in excess of 2mA. This pin is
driven low as an output when an internal reset condition occurs.
42
51
HFXIN
High-Frequency Crystal Input.
Connect an external crystal or resonator between HFXIN and
HFXOUT as the high-frequency system clock. Alternatively, HFXIN is the input for an external,
high-frequency clock source when HFXOUT is floating.
41
50
HFXOUT
High-Frequency Crystal Output/Input.
Connect an external crystal or resonator between HFXIN
and HFXOUT as the high-frequency system clock. Alternatively, float HFXOUT when an external,
high-frequency clock source is connected to the HFXIN pin.
