Accessing the FLASH Data Memory Area
performed for the 8000H to FFFFH area. Therefore, to write the data memory of FLASH,
the program being executed should be jumped to RAM area or should be jumped to the
support program in BOOT-ROM. For details about the support program in BOOT-ROM,

wait) for control circuit of Flash memory is executed (The write data counter is also
initialized). If WINT = “1” is detected in the nonmaskable interrupt service routine, a write
is not completed successfully. So, it is necessary to try a write again. The warm-up period is
