4. You cannot write in the page programming mode. Always set the equipment to the byte
5. The capacity of the on-chip ROM is 32 kbytes, so the data of PROM writer addresses
6. When write errors occur on consecutive addresses, stop writing. Check to see if there are any

After programming, we recommend letting the device stand at high temperature (125–150 C) for
24–48 hours to increase the reliability of data retention. Letting it stand at high temperature is a
type of screening method that can get rid of initial data retention defects of the on-chip PROM's
memory cell within a short period of time. Figure 16.6 shows the flow from programming of the
on-chip PROM, including screening, to mounting on the device board.
If abnormalities are found when the program is written and verified or the program is read and
checked after the writing/verification or letting the chip stand at high temperature, contact
Hitachi's engineering departments.
