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.
