19.5.1 Precautions on all PROM versions
When programming to the built-in PROM, high voltage is required. Accordingly, be careful not to apply
excessive voltage to the microcomputer. Furthermore, be especially careful during power-on.
19.5.2 Precautions on One time PROM version
One time PROM versions shipped in a blank, of which built-in PROMs are programmed by users, are also
provided.
For these microcomputers, a programming test and screening are not performed in the assembly process
and the following processes. To improve their reliability after programming, we recommend to program and
test as the flow shown in Figure 19.5.1 before use.
