20.11 CAN I/O Mode
In CAN I/O mode, the user ROM area can be rewritten while the MCU is mounted on-board by using a CAN
programmer which is applicable for the M16C/29 group. For more information about CAN programmers,
contact the manufacturer of your CAN programmer. For details on how to use, refer to the user’s manual
included with your CAN programmer.
Table 20.9 lists pin functions for CAN I/O mode. Figures 20.19 and 20.20 show pin connections for CAN I/
O mode.
20.11.1 ID code check function
This function determines whether the ID codes sent from the CAN programmer and those written in the
flash memory match.(Refer to 20.3 Functions To Prevent Flash Memory from Rewriting.)
Note
The CAN I/O mode is not available in M16C/29 T-ver./V-ver.
