Launching Programming
Status of the Flash Memory
Selecting FM0/FM1
4136B–USB–09/03
The other memory spaces (user, extra row, hardware security) are made accessible in
the code segment by programming bits FMOD0 and FMOD1 in FCON register in accor-
dance with Table 34. A MOVC instruction is then used for reading these spaces.
Table 34. FM0 Blocks Select Bits
FPL3:0 bits in FCON register are used to secure the launch of programming. A specific
sequence must be written in these bits to unlock the write protection and to launch the
programming. This sequence is 5 followed by A. Table 35 summarizes the memory
spaces to program according to FMOD1:0 bits.
Table 35. Programming Spaces
The Flash memory enters a busy state as soon as programming is launched. In this
state, the memory is not available for fetching code. Thus to avoid any erratic execution
during programming, the CPU enters Idle mode. Exit is automatically performed at the
end of programming.
Note:
The bit FBUSY in FCON register is used to indicate the status of programming.
FBUSY is set when programming is in progress.
The bit ENBOOT in AUXR1 register is used to choose between FM0 and FM1 mapped
up to F800h.

Interrupts that may occur during programming time must be disabled to avoid any spuri-
