• Manufacturer Part Number: SAB80C517-M16
• Description: 8-Bit CMOS Single-Chip Microcontroller
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

On-Chip Peripheral Components
To drive the SAB 80 C517 with an external clock source, the external clock signal is to be applied
to XTAL2, as shown in figure 7-67. XTAL1 has to be left unconnected. A pullup resistor is
V
suggested (to increase the noise margin), but is optional if
of the driving gate corresponds to
OH
V
the
I
specification of XTAL2.
