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.
89, Fig. 90 and Fig. 91 show the pin connections.
Refer to Fig. 92 and Fig. 93 for example of a connection with a
serial 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.

Function
Apply 1.8 to 5.5V to VCC, and 0V to VSS.
____________
Reset input pin for active “L”. Reset occurs when RESET pin is hold at
an “L” level for 16 cycles or more of XIN.
Set the same termination as the single-chip mode.
Input the reference voltage of A/D converter to VREF.
Input “H” or “L” level signal or leave the pin open.
QzROM programmable power source pin.
Serial data I/O pin.
Serial clock input pin.
Read/program pulse input pin.
