•
PG-FP3 pins not wired
Keep in mind the following points:
•
Open the CLK signal of the PG-FP3 to supply a clock to the microcontroller from the target.
•
Open the SCK signal when using a UART.
•
Open the SO signal when using IIC.
•
Open the HS signal when not using SIO + handshaking.
The pin configuration of the target interface connector and specifications of the interface cable are given below.
