5.2.4

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 Section 6: READY/BUSY

status.

For the meanings of An and Xn, please see Table 4, Table 5 and Table 6.

5.2.5

Erase All

The Erase All Memory (ERAL) instruction erases the whole memory (all memory bits are set

to 1). The format of the instruction requires that a dummy address be provided. The Erase

cycle is conducted in the same way as the Erase instruction (ERASE). The completion of

the cycle can be detected by monitoring the READY/BUSY line, as described in Section 6:

READY/BUSY status.
