Memory
This program sequence is repeated throughout the memory until all data is programmed.
2.5.6 FLASH Protection
Due to the ability of the on-board charge pump to erase and program the FLASH memory in the target
application, provision is made to protect pages of memory from unintentional erase or program operations
due to system malfunction. This protection is done by use of a FLASH block protect register (FLBPR).
The FLBPR determines the range of the FLASH memory which is to be protected. The range of the
protected area starts from a location defined by FLBPR and ends to the bottom of the FLASH memory
($FFFF). When the memory is protected, the HVEN bit cannot be set in either erase or program
operations.
38
The time between each FLASH address change (step 6 to step 6), or the
time between the last FLASH addressed programmed to clearing the PGM
bit (step 6 to step 9), must not exceed the maximum programming time,
t
Programming and erasing of FLASH locations cannot be performed by
code being executed from the FLASH memory. While these operations
must be performed in the order shown, other unrelated operations may
occur between the steps.
The 48 bytes of user interrupt vectors ($FFD0–$FFFF) are always
protected, regardless of the value in the FLASH block protect register. A
mass erase is required to erase these locations.
