22.4 Example Connection for On-board Writing
Figure 22-2 shows example connections to perform on-board writing.
Figure 22-2 Example Connections for On-board Writing
Note 1: If other parts on a target board interfere with the UART communication in serial PROM mode, disconnect these
pins by using a jumper or switch.
Note 2: If the reset control circuit on a target board interferes with the startup of serial PROM mode, disconnect the circuit
by using a jumper, etc.
Note 3: For information on other pin settings, refer to "Table 22-3 Pin Functions in Serial PROM Mode".
