Erase Byte or Word
The Erase Byte or Word (ERASE) instruction sets the bits of the addressed memory byte (or
word) to 1. Once the address has been correctly decoded, the falling edge of the Chip
Select Input (S) starts the self-timed Erase cycle. The completion of the cycle can be
detected by monitoring the READY/BUSY line, as described in the READY/BUSY status
section.
