Table 2.3 lists the PB926EJ-S LED indicators and their function.
|5V OK||Green||D29||Indicates that the 5V power supply is on|
|3V3 OK||Green||D34||Indicates that the 3V3 power supply is on|
|Standby||Red||D39||Indicates that the PB926EJ-S is in standby mode and the power is off. This LED only functions when power is supplied to the board via connector J35|
Indicates that the PB926EJ-S is in configuration mode. Configuration mode is entered by fitting the CONFIG link J32 on the board and powering-up
The CONFIG link is a switch on some board versions.
|FPGA Config||Yellow||D6||Directly indicates the status of the FPGA Config pushswitch S4. LED is off when the switch is pressed|
|DEV CHIP Reconfig||Blue||D3||Directly indicates the status of the DEV CHIP Reconfig pushswitch S5. LED is off when the switch is pressed|
|Reset||Amber||D4||Directly indicates the status of the Reset pushswitch S2. LED is off when the switch is pressed|
|GP (User) Pushswitch||Green||D5||Directly indicates the status of the general purpose pushswitch S3. LED is off when the switch is pressed|
|GP (User) LEDs||Green||D12-18, D20||Eight general purpose LEDs. These LEDs are controlled individually by the lower eight bits of the SYS_LED register. See User switches and LEDs for further details|
|Ethernet||Green Yellow||J5||Ethernet activity indicators. These LEDs are integral to the Ethernet connector J5 and are configured by writing to a register in the LAN91C111 fast Ethernet controller. See Ethernet interface for further details|
|Global Done||Green||D8||Indicates that all the FPGA devices on the Logic Tiles have been configured|
|Local Done||Green||D7||Indicates that the PB926EJ-S FPGA device has been configured|
|USB Debug Busy||Amber||D22||Indicates that the embedded Real View ICE Micro Edition hardware is active|
|USB Debug On||Green||D23||Indicates that the embedded RealView ICE Micro Edition hardware is enabled|
