Do you have a from your programmer?
Allows you to read/write to the surface-mounted 8-pin IC. Note: Desoldering the chip with a hot-air rework station and placing it in an execution socket is highly recommended over using a test clip, as the board's parasitic capacitance often disrupts data signals during in-circuit operations.
