3.2 Basic Hints
These basic hints are useful for programming MSP430 devices or MSP430
devices on printed-wire boards (PWB).
- All V
CC
pins of an MSP430 device are tied together and connected to the
most positive terminal of the supply.
- All V
SS
pins of an MSP430 device are tied together and connected to the
most negative terminal of the supply.
- The interface should supply the MSP430 with proper conditions according
to the device data sheet, in terms of current, voltage levels, and timing
conditions.
- Make sure the proper signal connections (see Section 3.3) are made.
- Short cables to interconnect the interface to the MSP430 device or PWB;
less than 20 cm is recommended.
- Ensure low-impedance interconnections − especially for the path of the
programming and fuse blow voltage.
- When a device with a transparent window (MSP430E3xx family) is
programmed, the window should be already covered with an opaque label
while the device is programmed. Since ambient light contains the correct
wavelength for erasure, keep the transparent window covered after the
device is programmed.
