CLOCK SYSTEM (Cont’d)

Figure 11. Clock Circuit Block Diagram

Figure 12. Maximum Operating Frequency (fMAX) versus Supply Voltage (VDD)

Notes:

1. In this area, operation is guaranteed at the quartz crystal frequency.

2. When the OSG is disabled, operation in this area is guaranteed at the crystal frequency. When the OSG

is enabled, operation in this area is guaranteed at a frequency of at least fOSG Min.

3. When the OSG is disabled, operation in this area is guaranteed at the quartz crystal frequency. When

the OSG is enabled, access to this area is prevented. The internal frequency is kept a fOSG.

4. When the OSG is disabled, operation in this area is not guaranteed

When the OSG is enabled, access to this area is prevented. The internal frequency is kept at fOSG.
