6.8.3
The program/erase/verify specifications in PROM mode are the same as for the standard
HN28F101 flash memory. The H8/3644F, H8/3643F, and H8/3642AF do not have a device
recognition code, so the programmer cannot read the device name automatically. Table 6.13 shows
how the different operating modes are selected when using PROM mode.
