Flash program memory and data EEPROM (FLASH) RM0367
110/1043 RM0367 Rev 7
Bit 8 FIX
0: An erase phase is automatically performed, when necessary, before a program operation
in the data EEPROM and the Option bytes areas. The programming time can be:
Tprog (program operation) or 2 * Tprog (erase + program operations).
1: The program operation is always performed with a preliminary erase and the
programming time is: 2 * Tprog.
Note: This bit can be modified when PELOCK is 0. It is reset when PELOCK is set.
Bits 7:5 Reserved, must be kept at reset value
Bit 4 DATA
0: Data EEPROM not selected.
1: Data memory selected.
Note: This bit can be modified when PELOCK is 0. It is reset when PELOCK is set.This bit is
not very useful as the page and word have the same size in the data EEPROM, but it is
used to identify an erase operation (by page) from a word operation.
Bit 3 PROG
This bit is used for half-page program operations and for page erase operations in the Flash
program memory.
0: The Flash program memory is not selected.
1: The Flash program memory is selected.
Note: This bit can be modified when PELOCK is 0. It is reset when PELOCK is set.
