Note:
Note:
Note:
Does not include the time until each operation of the flash memory is started after instructions are executed by software.
The lower-limit frequency of FCLK is 1 MHz during programming or erasing the flash memory. When using FCLK at below
4 MHz, the frequency can be set to 1 MHz, 2 MHz, or 3 MHz. A non-integer frequency such as 1.5 MHz cannot be set.
The frequency accuracy of FCLK must be ±3.5%. Confirm the frequency accuracy of the clock source.
