Format of On-chip Debug Option Byte
The format of on-chip debug option byte is shown below.
Figure 26 - 7 Format of On-chip Debug Option Byte (000C3H/010C3H)
Note
Set the same value as 000C3H to 010C3H when the boot swap operation is used because 000C3H is
replaced by 010C3H.
Caution
Bits 7 and 0 (OCDENSET and OCDERSD) can only be specified a value.
Be sure to set 000010B to bits 6 to 1.
Remark
The value on bits 3 to 1 will be written over when the on-chip debug function is in use and thus it will become
unstable after the setting.
However, be sure to set the default values (0, 1, and 0) to bits 3 to 1 at setting.
