HPPCI-ICE LEDs
Four LEDs are located on the pod enclosure ( Figure 2-1 ), and five LEDs
are located on the daughter board ( Figure 2-2 ).
Pod LEDs
• 1.8V LED – In auto detection mode, this LED signifies that a
target VDDIO of 1.8V has been detected on the JTAG header
(pin 5) on the processor target board, and the HPPCI-ICE drives
all signals at 1.8V compliant levels.
• 2.5V LED – In auto detection mode, this LED signifies that a
target VDDIO of 2.5V has been detected on the JTAG header
(pin 5) on the processor target board, and the HPPCI-ICE drives
all signals at 2.5V compliant levels.
