ratio) +
The actual registers (CLKSMN and CLKSMX) setting value is calculated by above the
configuration values
The following shows the calculation formulas and register setting examples when f
MHz (assuming the guaranteed oscillation frequency error is
generated.
Example of calculation for the configuration frequency
How to set the CLKSMN and CLKSMX registers
The configuration frequency = (frequency) + (frequency error ratio) + (OFD circuit error
therefore recommended to set CLKSMN and CLKSMX to approximately
When the oscillation clock frequency goes outside the specified range, an OFD reset is
注) 本周波数検知回路は発振周波数の高調波、低調波発振を検知するための回路です。発振子および発振器の
The OFD of this product is capable of detecting f
Frequency (Low) = 24 MHz*(1-10%) = 21.6 MHz
Frequency (High) = 24 MHz*(1+10%) = 26.4 MHz
Frequency (Low) = 21.6 MHz
Frequency (High) = 26.4 MHz
