The ERASE instruction forces all data bits of the
specified address to the logical ‘1’ state. CS is brought
low following the loading of the last address bit. This
falling edge of the CS pin initiates the self-timed
programming cycle, except on ‘93C’ devices where the
rising edge of CLK before the last address bit initiates
the write cycle.
