Cautions about operation!
• Electrical properties presented on the data sheet for the mask ROM and ZTAT^TM versions will surely
and sufficiently satisfy the standard values. However, real capabilities, operation margin, noise margin,
and other properties may vary depending on differences of manufacturing processes, internal wiring
patterns, etc. Therefore, it is requested for users to carry out an evaluation test for each product on an
actual system under the same conditions to see its operation.
• Memory register, data area, and stack area values are unstable immediately after power is turned on.
They must be initialized before use.
