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.
