Name and Functions
Power supply: All V_CC pins should be
connected to the system power
supply (+5 V)
Ground: All V_SS pins should be
connected to the system power
supply (0 V)
Analog power supply: This is the
power supply pin for the A/D
converter. When the A/D converter is
not used, connect this pin to the
system power supply (+5 V).
Analog ground: This is the A/D
converter ground pin. It should be
connected to the system power
supply (0 V).
LCD power supply: These are
power supply pins for the LCD
controller/ driver. A built-in resistor
divider is provided for the power
supply, so these pins are normally left
open.
Power supply conditions are
V_CC ≥ V₁ ≥ V₂ ≥ V₃ ≥ V_SS.
This pin connects to a crystal or
ceramic oscillator, or can be used to
input an external clock.
See section 4, Clock Pulse
Generators, for a typical connection
diagram.
This pin connects to a 32.768-kHz
crystal oscillator.
See section 4, Clock Pulse
Generators, for a typical connection
