Datasheet
• Error Response, H'D0, (one byte): Error response for 128-byte programming
• ERROR: (one byte): Error code
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 14.26.
