GPIO LEDs (LED3–5)
Three LEDs are connected to the general-purpose I/O pins of the proces-
sor (see
Table 2-12 ). The LEDs are active high and are
ON
(amber) by
writing a
1
to the correct processor signal.
Reset LED (LED6)
When
LED6
is
ON
(red), it indicates that the master reset of all the major
ICs is active. The reset LED is controlled by the Analog Devices
ADM6315 supervisory reset circuit.
TARGET_RESET
is a signal driven from
an emulator. EI3 extender cards can also drive a reset as an input to this
reset circuit. A master reset is asserted by pressing
SW2
which activates
LED6
. For more information, see Reset Push Button (SW2) .
Power LED (LED2)
When
LED2
is
ON
(green), it indicates that power is being supplied to the
board properly. For more information, see Power Architecture .
SYS_FAULT LED (LED1)
When
SYS_FAULT LED
(
LED1
) (red) is
ON
, it indicates a system fault. For
more information, refer to the hardware reference manual.
