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 13 lists the pin description (QzROM writing mode) and Fig-
ure 58 and Figure 59 show the pin connections.
Refer to Figure 60 and Figure 61 for examples 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.
Table 13 Pin description (QzROM writing mode)
Apply 1.8 to 5.5 V to VCC, and 0 V 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.
Connect AVss to Vss.
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.
