23.4 Setting of Option Byte
addition to describing to the source. When doing so, the contents set by using the linker option take precedence,
even if descriptions exist in the source, as mentioned below.
010C3H. Describe to 010C0H to 010C3H, therefore, the same values as 000C0H to 000C3H as follows.
The user option byte and on-chip debug option byte can be set using the RA78K0R or PM+ linker option, in
See the RA78K0R Assembler Package User’s Manual for how to set the linker option.
A software description example of the option byte setting is shown below.
When the boot swap function is used during self programming, 000C0H to 000C3H is switched to 010C0H to

name of the CSEG pseudo instruction. To specify the option byte to 010C0H to 010C3H in order
to use the boot swap function, use the relocation attribute AT to specify an absolute address.
