○
Setting of flash operation mode
Make the setting depending on the main system clock frequency (f
used.
● LV (low voltage main) mode
● LS (low speed main) mode
● HS (high speed main) mode
○
Setting of the frequency of the high-speed on-chip oscillator
● Select from 32 MHz/24 MHz/16 MHz/12 MHz/8 MHz/6 MHz/4 MHz /3 MHz/2 MHz/1 MHz (TYP.).
Caution Set the same value as 000C2H to 010C2H when the boot swap operation is used because
000C2H is replaced by 010C2H.

○
Control of on-chip debug operation
● On-chip debug operation is disabled or enabled.
○
Handling of data of flash memory in case of failure in on-chip debug security ID authentication
● Data of flash memory is erased or not erased in case of failure in on-chip debug security ID authentication.
Caution Set the same value as 000C3H to 010C3H when the boot swap operation is used because
