• Manufacturer Part Number: saf-xc888cm-8ffi5v
• Description: 8-bit Single-chip Microcontroller
• Manufacturer: Infineon Technologies Corporation

3.8.2
The CGU generates all clock signals required within the microcontroller from a single
clock,
modules are as follow:
•
•
•
•
In addition, different clock frequencies can be output to pin CLKOUT (P0.0 or P0.7). The
clock output frequency, which is derived from the clock output divider (bit COREL), can
further be divided by 2 using toggle latch (bit TLEN is set to 1). The resulting output
frequency has a 50% duty cycle.
XC886/888.
