Example Circuit Application for The Standard Serial I/O Mode
The below figure shows a circuit application for the standard serial I/O mode. Control pins will vary ac-
cording to peripheral unit (programmer), therefore see the peripheral unit (programmer) manual for more
information.

(1) Control pins and external circuitry will vary according to peripheral unit (programmer). For
more information, see the peripheral unit (programmer) manual.
(2) In this example, the microprocessor mode and standard serial I/O mode are switched via a
switch.
