19.4 Usage Note
The ZTAT version and the mask ROM version satisfy the electrical properties given in this
document. However, effective values of the electrical properties, the operating margin, and the
noise margin may differ with the manufacturing processes, on-chip ROM, and layout patterns.
When conducting a system evaluation test using the ZTAT version, conduct a similar evaluation
test of the mask ROM version before it replaces the ZTAT version.
