26.3.2.5
The block erase command is used to erase a specified block.
By writing the command code xx20h in the first bus cycle and xxD0h to the highest-order even address of a
block to be erased in the second bus cycle, an erase operation (erase and verify) starts on the specified block.
The FMR00 bit in the FMR0 register can be used to determine whether an erase operation has been completed
or not. The FMR00 bit becomes 0 (busy) during the erase operation, and becomes 1 (ready) when the erase
operation is completed.
After the erase operation is completed, the FMR07 bit in the FMR0 register is used to determine whether the
erase operation is completed successfully or not. (Refer to 26.3.5 Full Status Check for details.)
Figure 26.10 shows a flow chart of block erase command.
The lock bit can protect each block from being erased inadvertently. (Refer to 26.3.3 Data Protect Function
for details.)
In EW1 mode, do not execute this command to the block where the rewrite control program is stored.
In EW0 mode, the flash memory enters read status register mode when an erase operation starts.
