QzROM Writing Mode
In the QzROM writing mode, the user ROM area can be
rewritten while the microcomputer is mounted on-board by using
a serial programmer which is applicable for this microcomputer.
Table 9 lists the pin description (QzROM writing mode) and
Figure 68 to Figure 70 show the pin connections.
Refer to Figure 71 and Figure 72 for examples of a connection
with a serial programmer.
Contact the manufacturer of your serial programmer for serial
programmer. Refer to the user ’s manual of your serial
programmer for details on how to use it.
