The ERASE instruction forces all data bits of the speci-
fied 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 program-
ming cycle, except on ‘93C’ devices where the rising
edge of CLK before the last address bit initiates the
write cycle.
