Properly Installing the Programmer Hardware
1.3.5Integrated Circuit (IC) Insertion
ICs may be inserted or removed while power is applied to the programmer; however:
1)When using the microcontroller programmer, never use more than one IC socket at a time. Damage to the IC or the programmer could result.
2)Never insert or remove the IC while the red LED is on. Dam- age to the IC or the programmer could result.
3)TMS devices contain circuits to protect their inputs and out- puts against damage due to electrostatic discharges of up to 2 kV. However, you should employ the usual precautions when handling MOS devices, such as storing the device in conductive foam and grounding yourself when handling them.
For the microcontroller programmer, decide which of the sockets (U1, U2, U3, U4, or U5) to use for your device. Figure 1±3, shows the circuit board and IC sockets.
