Power supply
Power supply pins. Connect all these pins
to the system power supply. The chip does
not operate when some of these pins are
opened.
Ground
Ground pins. Connect all these pins to the
system power supply (0 V). The chip does
not operate when some of these pins are
opened.
Power supply Power supply pin for supplying power to
for PLL
on-chip PLL.
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.
System clock Supplies the system clock to external
output
devices.
Set the mode Set the operating mode. Inputs at these
pins should not be changed during
operation.
Protection
against write
operation into
flash memory
Pin for the flash memory. This pin is only
used in the F-ZTAT version. Programming
or erasing of flash memory can be
protected. This pin is used as Vcc in the
masked ROM version and ROM less
version.
