3. Programming/erasing state
Programming and erasure by the boot program take place in this state. The boot program is
made to transfer the programming/erasing programs to the on-chip RAM by commands from
the host. Sum checks and blank checks are executed by sending these commands from the
host.
These boot program states are shown in figure 24.18.
