4.4 Functional Description of the eZ430-Chronos Debug Interface
The eZ430-Chronos kit includes an USB emulator that provides full programming and debugging features
using its Spy-Bi-Wire (2-wire) interface. It features a back channel MSP430 application UART that may be
used independently of a debug session.
NOTE: Despite the fact that the watch module is equipped with a 6-pin connector, there is no UART
connection from the watch to the emulator as all pins of the CC430 are already used for
other purposes.
Supported devices:
• CC430F51xx
• CC430F61xx
• MSP430F20xx
• MSP430F21x2
• MSP430F22xx
• MSP430F41x2
• MSP430F54xx
• MSP430F54xxA
• MSP430F55xx
Connector J1 on the emulator (starting on top with pin 1) (see Figure 4-12).
• UART TX (from emulator to target)
• 3.6-V supply for target
• TEST/SBWTCK
• RST/SBWTDIO
• GND
• UART RX (from target to emulator)

4.4.1 MSP430 Application UART
The eZ430-Chronos emulator includes a back channel MSP430 Application UART that may be used
independently of a debug session. This allows the user to transfer serial data to a terminal window at a
fixed rate of 9600 bps with no flow control. Check the Device Manager for COM port assignment of the
MSP430 Application UART (for more details, see Section B.2).
