5.8.3 LED Signals

eZ-FET emulators show their operating states using two LEDs, one green and one red. Table 16 lists all available operation modes. The eZ-FET 2.0 has an additional yellow LDO LED, that illuminates when the LaunchPad is connected to a computer.

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.

Table 16. eZ-FET LED Signals

Power LED	Mode LED	LDO LED (eZ-FET 2.0 Only)	Function
		–	eZ-FET not connected to PC, or eZ-FET not ready; for example, after a major firmware update. Connect or reconnect eZ-FET to PC.
		–	eZ-FET connected and ready
		–	eZ-FET waiting for data transfer
		–	Ongoing data transfer – during active debug session
		–	An error has occurred; for example, target VCC over current. Unplug eZ-FET from target, and cycle the power off and on. Check target connection, and reconnect eZ-FET.
		–	Firmware update in progress. Do not disconnect eZ-FET while both LEDs are blinking.
–	–		The LDO target supply is active (the LDO is the default supply).
–	–		The EnergyTrace power supply is active.
