ERASE
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 ‘C’ devices where the rising
edge of CLK before the last address bit initiates the
write cycle.
The DO pin indicates the READY/BUSY status of the
device if CS is brought high after a minimum of 250 ns
low (T
CSL). DO at logical “0” indicates that program-
ming is still in progress. DO at logical “1” indicates that
the register at the specified address has been erased
and the device is ready for another instruction.
