•
•
384 Kbytes of P-Flash (Program Flash) memory, consisting of 2 physical Flash blocks, intended
primarily for nonvolatile code storage
32 Kbytes of D-Flash (Data Flash) memory, consisting of 1 physical Flash block, that can be used
as nonvolatile storage to support the built-in hardware scheme for emulated EEPROM, as basic
Flash memory primarily intended for nonvolatile data storage, or as a combination of both

MC9S12XE-Family Reference Manual Rev. 1.24
Table 26-1. Revision History
- Cleanup
- Updated Command Error Handling tables based on parent-child relationship
with FTM512K3
- Corrected Error Handling table for Full Partition D-Flash, Partition D-Flash,
and EEPROM Emulation Query commands
- Corrected P-Flash IFR Accessibility table
- Clarify single bit fault correction for P-Flash phrase
- Expand FDIV vs OSCCLK Frequency table
- Add statement concerning code runaway when executing Read Once
command from Flash block containing associated fields
- Add statement concerning code runaway when executing Program Once
command from Flash block containing associated fields
- Add statement concerning code runaway when executing Verify Backdoor
Access Key command from Flash block containing associated fields
- Relate Key 0 to associated Backdoor Comparison Key address
- Change “power down reset” to “reset”
- Add ACCERR condition for Disable EEPROM Emulation command
The following changes were made to clarify module behavior related to Flash
register access during reset sequence and while Flash commands are active:
- Add caution concerning register writes while command is active
- Writes to FCLKDIV are allowed during reset sequence while CCIF is clear
- Add caution concerning register writes while command is active
- Writes to FCCOBIX, FCCOBHI, FCCOBLO registers are ignored during
reset sequence
