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 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 pin for supplying power to
on-chip PLL.
On-chip PLL oscillator ground pin.
External capacitance pin for an on-chip
PLL oscillator.
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.
For connection to a crystal resonator. For
examples of crystal resonator connection
and external clock input, see section 4,
Clock Pulse Generator.
Supplies the system clock to external
devices.
Set the operating mode. Inputs at these
pins should not be changed during
operation.
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.
