Notice: This is not a final specification.
Some parametric limits are subject to change.
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 10 lists the pin description (QzROM writing mode) and
Figure 66 shows the pin connections.
Refer to Figure 67 and Figure 68 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.
