VLCD
LCD Bias-Control Voltage. Highest LCD drive voltage used with static bias. Connected
to an external source.

84
VLCD1
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.

VLCD2
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.

VADJ
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.

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.

71
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.
