Section 22 Flash Memory
22.3.2
Setting the FMCMDEN bit in FLMCR1 to 1 shifts the flash memory into the user programming
mode, in which commands can be accepted. Figure 22.2 shows how to set and clear the EW0
mode.
Programming and erasure are controlled through software commands. The flash memory state
after programming or erasure can be checked through FLMSTR or the status register.
