What Are ISP and Test Points?


### In-System Programming (ISP)

ISP involves programming or reprogramming the microcontroller or memory chip within a device without removing it from the circuit board. This technique is essential for:

- **Firmware Flashing: Directly updating or replacing the firmware on a chip.

- **Data Recovery: Accessing and recovering data from damaged devices.

- **Device Unlocking: Bypassing security locks and restrictions.


### Test Points

Test points are specific locations on a circuit board used for diagnostics and troubleshooting. These points allow technicians to:

- **Measure Signals: Check voltage levels and other electrical signals.

- **Access Hidden Features: Enable or disable features that are not easily accessible.

- **Perform Repairs: Identify and fix hardware issues efficiently.
