. Switches
The ML605 Evaluation board includes the following switches:
•
Power On/Off Slide Switch SW2
•
FPGA_PROG_B SW4 (active-Low)
•
SYSACE_RESET_B SW3 (active-Low)
•
System ACE CF CompactFlash Image Select DIP Switch S1 (active-High)
•
MODE, Boot EEPROM Select and CCLK Osc Enable DIP switch S2 (active-High)
Power On/Off Slide Switch SW2
SW2 is the ML605 board main power on/off switch. Sliding the switch actuator from the
off to on position applies 12V power from either J60 (6-pin Mini-Fit) or J25 (4-pin ATX)
power connector to the VCC12_P power plane via the 1 m
Ω
1% 3W series current sense
resistor R346. See
for further details on 12V input current sensing.
Green LED DS25 will illuminate when the ML605 board power is on. See section
for details on the onboard power system.
