3. Programming/erasing state
These boot program states are shown in figure 24.18.
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.
