Example Circuit Application for Standard
Serial I/O Mode
Figure 83 shows a circuit application for the standard serial I/O
mode. Control pins will vary according to a programmer, therefore
see a programmer manual for more information.

Notes 1: Control pins and external circuitry will vary according to peripheral unit. For more
information, see the peripheral unit manual.
2: In this example, the Vpp power supply is supplied from an external source (writer). To use
the user’s power source, connect to 4.5 V to 5.5 V.
3: It is necessary to apply Vcc to SCLK pin only when reset is released.
