system power supply.
power. Connect this pin to Vss through an
external capacitor (that is located near this pin)
to stabilize internal step-down.
Ground pins. Connect all these pins to the
system power supply (0V).
For connection to a crystal resonator. An
external clock can be supplied from the EXTAL
pin. For an example of crystal resonator
connection, see section 21, Clock Pulse
Generator.
These pins set the operating mode. Inputs at
these pins should not be changed during
operation.
Reset pin. When this pin is low, the chip is reset.
When this pin is low, a transition is made to
hardware standby mode.
Pin for use by flash memory.
