2. Workaround:

To avoid the continuous execution of Instruction codes which addresses from 001FFFCH to 0020000H, please allocate 16

bytes data of all “0” in the address of 001FFF0H to 001FFFFH.

(Example of settings for data allocation)

The following shows examples for data allocation by using Renesas IDE PM+ (CubeSuite+).

Constant array of “dummy” is defined as 16 bytes data of all “0”, and it is allocated from 001FFF0H to 001FFFFH.

Please add the C source file and Link directive file as shown below.

C source) Add the following codes as constant array of “dummy”.

Link directive) Add the following codes of “DUMMY_CONST”, “TEXT2” and “ROMP”

(Note 1) Regarding .text2 description, please assign user’s object file name (xxx.o, yyy.o and so on).

These user’s object files will be allocated upward to 0020000H.

#pragma section const "dummy" begin

const int ary[4]={0x00, 0x00, 0x00, 0x00};

#pragma section const "dummy" end
