CHAPTER 26 OPTION BYTE
Page 804 of 920
Figure 26 - 6 Format of Option Byte (000C2H/010C2H)
Note
Set the same value as 000C2H to 010C2H when the boot swap operation is used because 000C2H is
replaced by 010C2H.
Caution 1. Be sure to set bit 5 to 1.
Caution 2. The operating frequency range and operating voltage range depend on each operating mode of the
flash memory. See 31.4 AC Characteristics for details.
Address: 000C2H/010C2H
