A.1 Hardware FAQs

1.The state of the device (CPU registers, RAM memory, etc.) is undefined following a reset. Exceptions to the above statement are that the PC is loaded with the word at 0xFFFE (i.e., the reset vector), the status register is cleared, and the peripheral registers (SFRs) are initialized as documented in the device family user's guides. The CCE/CCS debugger and C-SPY reset the device after programming it.

2.MSP430F22xx Target Socket Module (MSP-TS430DA38) – Important Information

Due to the large capacitive coupling introduced by the device socket between the adjacent signals XIN/P2.6 (socket pin 6) and RST/SBWTDIO (socket pin 7), in-system debugging can disturb the LFXT1 low-frequency crystal oscillator operation (ACLK). This behavior applies only to the Spy-Bi-Wire (2-wire) JTAG configuration and only to the period while a debug session is active.

Workarounds:

•Use the 4-wire JTAG mode debug configuration instead of the Spy-Bi-Wire (2-wire) JTAG configuration. This can be achieved by placing jumpers JP4 through JP9 accordingly.

•Use the debugger option "Run Free" that can be selected from the Advanced Run drop-down menu (at top of Debug View). This prevents the debugger from accessing the MSP430 while the application is running. Note that, in this mode, a manual halt is required to see if a breakpoint was hit. See the IDE documentation for more information on this feature.

•Use an external clock source to drive XIN directly.

3.With current interface hardware and software, there is a weakness when adapting target boards that are powered externally. This leads to an accidental fuse check in the MSP430. This is valid for PIF and UIF but is mainly seen on UIF. A solution is being developed.

Workarounds:

•Connect RST/NMI pin to JTAG header (pin 11), LPT/USB tools are able to pull the RST line, which also resets the device internal fuse logic.

•Use the debugger option "Release JTAG On Go" that can be selected from the IDE drop-down menu. This prevents the debugger from accessing the MSP430 while the application is running. Note that in this mode, a manual halt is required to see if a breakpoint was hit. See the IDE documentation for more information on this feature.

•Use an external clock source to drive XIN directly.

4.The 14-conductor cable connecting the FET interface module and the target socket module must not exceed 8 inches (20 centimeters) in length.

5.The signal assignment on the 14-conductor cable is identical for the parallel port interface and the

USB FET.

6.To utilize the on-chip ADC voltage references, C6 (10 ?F, 6.3 V, low leakage) must be installed on the target socket module.

7.To utilize the charge pump on the devices with LCD+ Module, C4 (10 ?F, low leakage) must be installed on the target socket module.

8.Crystals/resonators Q1 and Q2 (if applicable) are not provided on the target socket module. For MSP430 devices that contain user-selectable loading capacitors, the effective capacitance is the selected capacitance plus 3 pF (pad capacitance) divided by two.

9.Crystals/resonators have no effect upon the operation of the tool and the CCE/CCS debugger or C-SPY (as any required clocking/timing is derived from the internal DCO/FLL).

10.On 20-pin and 28-pin devices with multiplexed port/JTAG pins (P1.4 to P1.7), to use these pin in their port capacity:

For CCE/CCS: "Run Free" (in Run pull-down menu at top of Debug View) must be selected.

For C-SPY: "Release JTAG On Go" must be selected.

11.As an alternative to sharing the JTAG and port pins (on 20 and 28 pin devices), consider using an MSP430 device that is a "superset" of the smaller device. A very powerful feature of the MSP430 is that the family members are code and architecturally compatible, so code developed on one device (for example, one without shared JTAG and port pins) ports effortlessly to another (assuming an equivalent set of peripherals).
