Flash EEPROM 256K
Flash Data
Memory Map
Since the address range of the flash module is larger than the 64K
(16-bit) native address space of the STAR12 the modules will be
mapped through an address window from $8000–$BFFF in 16K byte
blocks. The additional address bits are located in the PPAGE register.
