Table 25-1. Revision History
- Changed terminology from ‘word program’ to “Program P-Flash’ in the BDM
unsecuring description,
- Added requirement that user not write any Flash module register during
execution of commands ‘Erase All Blocks’,
Flash’,
- Added statement that security is released upon successful completion of
command ‘Erase All Blocks’,
- Corrected Error Handling table for Load Data Field command
- 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
