5.6.4 LED Signals
The MSP-FET shows its operating states using two LEDs, one green and one red. Table 5 lists all
available operation modes. An or icon indicates that the LED is off, an or icon indicates that
the LED is on, and an or icon indicates that the LED flashes.

over current. Unplug MSP-FET from target, and cycle the
power off and on. Check target connection, and reconnect MSP-FET.
Firmware update in progress. Do not disconnect MSP-FET while both LEDs are blinking slowly.
FPGA update in progress. Do not disconnect MSP-FET while both LEDs are blinking rapidly.
5.6.5 Hardware
