2.4 ERASE

The ERASE instruction forces all data bits of the

specified address to the logical ‘1’ state. 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 (TCSL). DO at logical ‘0’ indicates that programming

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.

Note:

Issuing a Start bit and then taking CS low

will clear the READY/BUSY status from

DO.
