Erasing Program Memory in
Low-Voltage Systems
The procedure for erasing program memory (all code
memory and data memory) in low-voltage systems
(with VDD between 2.5 volts and 4.5 volts) is quite
different than the procedure for erasing program
memory in normal-voltage systems. Instead of using a
Bulk Erase operation, each region of memory must be
individually erased by row. Namely, all of the code
memory, executive memory and data memory must be
erased one row at a time. This procedure is detailed in
Due to security restrictions, the FBS, FSS and FGS
register cannot be erased in low-voltage systems.
Once any bits in the FGS register are programmed to
‘0’, they can only be set back to ‘1’ by performing a Bulk
Erase in a normal-voltage system. Alternatively, a Seg-
ment Erase operation can be performed instead of a
Bulk Erase.
Normal-voltage systems can also be used to erase
program memory as shown in Table 11-5. However,
since this method is more time-consuming and does
not clear the code-protect bits, it is not recommended.
Note:
Program memory must be erased before
writing any data to program memory.
