User target recommendation circuit
A recommended sample of user target MCU peripheral circuit for RX66T is shown in Fig5.1.
Fig5.1
User Target Peripheral Circuit Example
（
For RX66T
）
1: If the user peripheral circuit is an output circuit, you should disconne ct by jumper to avoid output collision
when executing serial I/O mode. (see Fig5.)
2: EFP LC side reset output is an open collector therefore connect to the RESET pin with 1kΩ pull -up resistor for
open collector output. If the reset circuit is CMOS output, disconnect by jumper as described in Notes 1,
or connect the EFP-LC side T_RESET signal to reset circuit input.
By TXD from a writer, RXD and in combination in RESET signal output timing, a serial input and output
mode entry is performed. Please become less than 500ns in the L → H output timing of TXD, RXD and
the RESET signal.
3: Please connect the VCL terminal to GND through capacitor (0.47uF).
