Writing/verification
Programming of the built-in program ROM employs a high speed programming method. With this method,
high speed writing is effected without voltage stress to the device or without damaging the reliability of the
written data.
A basic programming flow chart is shown in figure 96 and a timing chart in figure 97.
For precautions for PROM writing procedure, refer to Section 2, "Characteristics of ZTAT
