Section 23 Flash Memory
• Erasure
Erasure is performed by issuing the erasure selection command and then one or more block
erasure commands.
Firstly, the host sends the erasure selection command to select erasure; after that, it sends a block
erasure command to actually erase a specific block. To erase multiple blocks, send further block
erasure commands. To terminate erasure, the host should send a block erasure command with the
block number H'FF. After this, the boot program waits for the next programming/erasure selection
command.
The sequence of erasure by the erasure selection command and block erasure command is shown
in figure 23.27.
