18.9.3 Operation in PROM Mode
www.DataSheet4U.com
The program/erase/verify specifications in PROM mode are the same as for the standard
HN28F101 flash memory. Table 18-20 indicates how to select the various operating modes. The
H8/3048F does not have a device recognition code, so the programmer cannot read the device
name automatically.
