Notes to
(1) Connect these pull-up resistors to the V
(2) Power up the V
(3) Pin 6 of the header is a V
(4) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL for AS
(5) Power up the V
(6) You must place the diodes and capacitors as close as possible to the Cyclone IV device. Altera recommends using
(7) These pins are dual-purpose I/O pins. The nCSO pin functions as FLASH_nCE pin in AP mode. The ASDO pin
(8) Resistor value can vary from 1 k to 10 k..
(9) Only Cyclone IV GX devices have an option to select CLKUSR (40 MHz maximum) as the external clock source for
device. For this value, refer to the
ByteBlasterMV download cable, this pin is a no connect. When using the USB-Blaster and ByteBlaster II cables, this
pin is connected to nCE when it is used for AS programming, otherwise it is a no connect.

Third-party programmers must switch to 2.5 V. Pin 4 of the header is a V
The MasterBlaster cable can receive power from either 5.0- or 3.3-V circuit boards, DC power supply, or 5.0 V from
the USB cable. For this value, refer to the
the Schottky diode, which has a relatively lower forward diode voltage (VF) than the switching and Zener diodes, for
effective voltage clamping.
