C.2 Sector Structure of 1M Bit Flash Memory
Sector structure of 1M bit flash memory in MB90F583 is shown in Figure C.2a. The address in the
Figure C.2a shows upper and lower address of each sector. When accessing from CPU, SA0 is set in the
FE bank register and SA1~4 are set in the FF Bank register.

The programmer address is equivalent to the CPU address map where data is
programmed to or erased from flash memory by the parallel writer (Minato Elec-
tronic: Model 1890A). When programmed to or erased from the flash memory by
a general-purpose programmer, this address is needed to specified.
