Notes:
1. Control pins and external circuitry will vary depending on the programmer.
For more information, refer to the programmer manual.
2. In this example, modes are switched between single-chip mode and standard
serial I/O mode by controlling the CNVSS input with a switch.
3. If in standard serial I/O mode 1 there is a possibility that the user reset
signal will go low during serial I/O mode, break the connection between
the user reset signal and RESET pin by using, for example, a jumper switch.
