k. Hardware Summary and Precautions
•
Connect pull-down resistors to RXD and CNVss lines.
•
Connect Reset line to the target MCU Reset pin or the target board’s reset circuit.
•
If EPM or CE lines are used as input pins, isolate the driving circuit from the 10-pin header using
a 1Kohm resistor.
•
If possible, avoid using the boot SIO/UART pins for other purposes.
•
Table 7.1 lists the M16C Flash MCU’s supported, CE or EPM pin support, the boot UART/SIO,
DBC interrupt support, and the no. of breakpoints that can be set in KD30.
