Control pins and external circuitry vary with the serial programmer. Refer to the user's manual included with the serial programmer. 2. In this example, a selector controls the voltage applied to the CNVSS pin to switch between in single-chip mode and in standard serial I/O mode. 3. In standard serial I/O mode 1, if the user reset signal becomes "L" while the microcomputer is communicating with the serial programmer, break the connection between the user reset signal and the RESET pin by, for example, a jumper selector.

Figure 25.18 shows an example of a circuit application serial I/O mode 2. Figure 25.19 shows an example of a circuit applica- tion serial I/O mode 3. Refer to the user's manual of your serial programmer to handle pins controlled by the serial programmer. Figure 25.15 Circuit Application in Standard Serial I/O Mode 1 |
