4.2 Mask Set K98M Clocking Scheme Worksheet
Figure 5 displays the mask set K98M Clocking Scheme worksheet, which shows the various frequencies, dividers,
and multipliers used in the MSC8126 clock module. It requires three entries:
Figure 5 depicts an example with a clock in (
C6), and a max core frequency of 400 MHz (cell C7). Error messages are shown in cell A10. If there are no error
messages, cell A10 is left blank. All values changed in the Clock Mode Chart worksheet do not change the
Clocking Scheme worksheet, and vice versa.
