The following are examples of interface circuits. Refer to the recommended design for the connection of pins in the
target device.
<1> SIO-H/S (3-wire clocked communication port, with handshake)
Figure 10-1. SIO-H/S Interface Circuit Example
Notes 1. Pin used in internal single-power-supply flash memory microcontroller
2. Pin used in internal two-power-supply flash memory microcontroller
<2> 78K0S (Single-wire UART)
Figure 10-2. Circuit Example for 78K0S (Single-wire UART)
Note These pins do not need to be shorted when using the FP5. Short them if necessary.
