Note 1. Does not include the time until each operation of the flash memory is started after instructions are executed by
the software.
Note 2. The lower-limit frequency of ICLK is 1 MHz during programming or erasing the flash memory. When using ICLK
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.
Note 3. The frequency accuracy of ICLK must be ±3.5% while programming or erasing the flash memory. Confirm the
frequency accuracy of the clock source.
