Power
You can power the MAX II development board from either the PCI bus or
the USB bus. If you are not using the board in the PCI slot of a PC, then
you must power the board from the USB bus. Jumper J8 is used to select
which bus powers the board. If the shunt is on pins 1 and 2, the board will
be powered via the USB bus. If the shunt is on pins 2 and 3, the board will
be powered via the PCI bus. Pin 1 of J8 is the pin closest to the LCD.
The PCI bus or the USB bus routes the power to six different regulators,
which power individual board components. The MAX II device is
powered from either a 2.5-V or a 3.3-V power supply. You select which
supply voltage to use (for V
load) of V
Power-Up Sequence
When you apply power to the MAX II development board, the 5.0-V
power supply powers up first, because it is the source for the 3.3-V/2.5-V
power supply. The 3.3-V/2.5-V V
increase or decrease the rate at which the V
