(10) Erasure
Erasure is performed with the erasure selection and block erasure command.
Firstly, erasure is selected by the erasure selection command and the boot program then erases the
specified block. The command should be repeatedly executed if two or more blocks are to be
erased. Sending a block-erasure command from the host with the block number H'FF will stop the
erasure operating. On completion of erasing, the boot program will wait for selection of
programming or erasing.
The sequences of the issuing of erasure selection commands and the erasure of data are shown in
figure 21.22.
(a) Erasure Selection
The boot program will transfer the erasure program. User MAT data is erased by the transferred
erasure program.
H'11: Checksum error
H'53: Programming error
Repeat
An error has occurred in programming and programming cannot be continued.
