How do I modify the Unit of programming for the data and the Unit of erasure for the data area in RA8D1 DATA FLASH

Question

Currently using RA8D1 DATA FLASH, Unit of programming for the data area:4/8/16 bytes To change the value to 8 bytes,Unit of erasure for the data area:***/128/256 bytes wants to be modified to 256 bytes, but there is no modification in FSP. The BSP_FEATURE_FLASH_HP_DF_WRITE_SIZE and BSP_FEATURE_FLASH_HP_DF_BLOCK_SIZE items in the BSP_FEATURE_H field are modified. Is there any way to modify it?

Hi Larry, 
 Thank you for your query! 
 The data flash programming and erase sizes for RA8D1 are hardware-defined and cannot be changed via FSP or by modifying BSP_FEATURE_FLASH_HP_DF_WRITE_SIZE and BSP_FEATURE_FLASH_HP_DF_BLOCK_SIZE. These macros reflect device capabilities but do not configure them. The supported units (4/8/16 bytes for programming and */128/256 bytes for erasing) are fixed per the hardware specification. 
 Kind regards,
