0
By writing command code "xxA7
erase (erase and verify) operation will run in all blocks. Do not access the flash memory or execute
the next command during auto erase operations.
The FMR00 bit in the FMR0 register indicates whether an auto erase operation is completed.
After the completion of an auto erase operation, the Status register indicates whether or not the auto
erase operation is completed as expected.
Figure 25.8 shows a flow chart of the erase all unlocked block command programming.
The lock bit can protect each block from being erased. (Refer to 25.3.6 Data Protect Function.)
