RL78G13 Data flash problem

Hello, I wondering if somebody have the same issue than me with the RL78 G13, I'm using the FDL RL78 TYPE 4 Lib for read write and erase data every was working fine until I setup the timer array unit.

 

If I left the TAUEN bit to 1 I can read the memory but if I try to write the program stops with the message "Break at address "0xd748" with no debug information available, or outside of program code." 

 

in the past I used the timer array unit and data flash libs with no problem but for some reason in this new project I had this issues.

I hope someone have information about this.

 

thanks in advance.
