CLKSMN and CLKSMX cannot be written while the frequency detection operation is enabled
(CLKSCR2 = “0xE4”) or writing to the OFD registers is disabled (CLKSCR1="0x06").
CLKSMN and CLKSMX are protected from write operation by writing “0x06” to CLKSCR1. These
registers can be read regardless of the setting of CLKSCR1.
The values to be set to CLKSMN and CLKSMX should be determined depending on the clock
frequencies to be used to satisfy the condition CLKSMN < CLKSMX. For how to calculate the CLKSMN
and CLKSMX set values, see examples in 3.26.3 “Description of Operation”.
Otherwise the internal reset might be always assert into the CPU. (Deadlock state)
The setting of CLKSMN and CLKSMX should be set with enough safe including several percent error.
