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 pro-grammer which is applicable for this microcomputer.
Table 24 lists the pin description (QzROM writing mode) and
Figure 53 shows the pin connections.
Refer to Figure 54 for examples of a connection with a serial pro-
grammer.
Contact the manufacturer of your serial programmer for serial
pro-grammer. Refer to the user’s manual of your serial
programmer for details on how to use it.
