Function to Protect Against Write due to Erroneous Instruction Recognition
The S-93C46B/56B/66B provides a built-in clock pulse monitoring circuit which is used to prevent an
erroneous write operation by canceling write instructions (WRITE, ERASE, WRAL, and ERAL) recognized
erroneously due to an erroneous clock count caused by the application of noise pulses or double counting
of clocks.
Instructions are cancelled if a clock pulse more or less than specified number decided by each write
operation (WRITE, ERASE, WRAL, or ERAL) is detected.

Example of S-93C46B

In products that do not include a clock pulse monitoring circuit, FFFF is
mistakenly written on address 00h. However the S-93C46B detects the overcount
and cancels the instruction without performing a write operation.
