R5F10PGJ : Data flash : Facing issue in accessing code flash from 0xF2000

Hi,

Am using R5F10PGJ with PFDL  V2.03.04.01

Am able to write data From 0xF1000 to 0xF1FFF (4KB).

But facing issue in accessing next area memory, i.e. next 4KB from 0xF2000 to 0xF2FFF.

Is there any another lib to do this.
