JTAG Debug Interface

The Pico E‐14 is equipped with a JTAG diagnostic port that allows real‐time debugging of hardware, firmware and software. Use of the external JTAG port disables four external GPIO pins as well as the internal JTAG loop back.

Some JTAG programs require the length of the instruction register (IR). The IR length is listed below for all devices in the JTAG chain.
