Power supply
Power supply pins. Connect all these pins
to the system power supply. The chip does
not operate normally when some of these
pins are open.
Ground
Ground pins. Connect all these pins to the
system power supply (0 V). The chip does
not operate normally when some of these
pins are open.
Power supply
for internal
power-down
External capacitance pins for internal
power-down power supply. Connect these
pins to VSS via a 0.47 μF (–10%/+100%)
capacitor (placed close to the pins).
Power supply
for PLL
External capacitance pin for internal
power-down power supply for an on-chip
PLL oscillator. Connect this pin to PLLVSS
via a 0.47 μF (–10%/+100%) capacitor
(placed close to the pin).
Ground for
PLL
On-chip PLL oscillator ground pin.
Capacitance External capacitance pin for an on-chip
for PLL
PLL oscillator.
External clock
For connection to a crystal resonator. (An
external clock can be supplied from the
EXTAL pin.) For examples of crystal
resonator connection and external clock
input, see section 4, Clock Pulse
Generator.
Crystal
For connection to a crystal resonator. For
examples of crystal resonator connection
and external clock input, see section 4,
Clock Pulse Generator.
Set the mode Set the operating mode. Inputs at these
pins should not be changed during
operation.
