Table 9 Pin description (QzROM writing mode)
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 Fig. 50
and Fig. 51 show the pin connections.
Refer to Fig. 52 and Fig. 53 for example of a connection with a se-
rial programmer.
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.
