Function
The SH79F082 provides SSP (Self Sector Programming) function, each sector can be sector erased (except the last sector,
sector 7) or programmed by the user’s code if the selected sector is not be protected. But once sector has been
programmed, it cannot be reprogrammed before sector erase.
The SH79F082 builds in a complex control flow to prevent the code from carelessly modification. If the dedicated conditions
are not met (IB_CON2-5), the SSP will be terminated.
