MC95FR332/432/364/464storage. In MC95FR332/432/364/464, two kinds of Data Memory are assigned to XDATA regionwhich are XRAM and Data EEPROM. So the address of two data memories do not duplicate. In otherwords, addresses higher than 03FF H accesses Data EEPROM if the addres space is assigned asData EEPROM.3FF HUpper1024 BytesInternal XRAM(Direct Addressing)000 HFigure 8.5 DATA MEMORY (XRAM)8.4 Data EEPROMAs described previously, MC95FR332/432/364/464 has 32KB/64KB of Program Memory calledFLASH. User software can divide this FLASH memory into two memory space, Program Memory andData EEPROM. If devided, lower address space from 0000 H is used for Program Memory and higheraddress space upto 7FFF H /FFFF H are used for Data EEPROM. Like External RAM, Data EEPROM isalso assigned to XDATA region, therefore the bottom address of Data EEPROM must higher than03FF H . Logically the maximum size of Data EEPROM is 31KB/63KB, addresses from 0400 H through7FFF H / FFFF H . After reset, the entire FLASH memory is assigned to Program Memory.36 January, 2012 Rev.2.0
