"What is set prior to constant being done in flash library environment? "

Latest Updated:08/28/2013


It is specified that the constant which indicates the frequency needs to be set prior to executing the function for initializing the flash library environment. What should be set?


Set a value that matches the operating frequency of the CPU in the user system. (It is not the operating frequency of high-speed on-chip oscillator.)
The setting made here is a value necessary for calculating the wait time used in the data flash libraries and this setting does not change the frequency setting of the microcontroller.

Since an inappropriate value may cause damage to the flash memory of the microcontroller, confirm the details on the setting in the manual.
