In CAN I/O mode, the CAN programmer supporting the M16C/6N Group (M16C/6N4) can be used to
rewrite the flash memory user ROM area in the MCU mounted on a board. For more information about the
CAN programmer, contact your CAN programmer manufacturer. Refer to the user's manual included with
your CAN programmer for instructions.
Table 21.8 lists pin functions in CAN I/O mode. Figures 21.17 and 21.18 show pin connections in CAN I/O
mode.
21.6.1 ID Code Check Function
The ID code check function determines whether the ID codes sent from the CAN programmer matches
those written in the flash memory. (Refer to 21.2 Functions to Prevent Flash Memory from Rewriting.)
1. When using CAN I/O mode, pins P0_0 to P0_7, P1_0 to P1_7 may become undefined while the P8_4 pin is “H”
and the RESET pin is “L”. If this causes a problem, apply “L” to the P8_4 pin.

Apply the Flash Program, Erase Voltage to VCC1 pin and VCC2
to VCC2 pin. The VCC apply condition is that VCC2 = VCC1.
Apply 0 V to VSS pin.
Connect to VCC1 pin.
Reset input pin. While RESET pin is “L” level, input 20 cycles or
longer clock to XIN pin.
Connect a ceramic resonator or crystal oscillator between XIN and
XOUT pins. To input an externally generated clock, input it to XIN
pin and open XOUT pin.
Connect this pin to VCC1 or VSS.
Connect AVCC to VCC1 and AVSS to VSS, respectively.
Enter the reference voltage for A/D and D/A converters from this
pin.
