Notes to Figure 9–15:
(1) Connect the pull-up resistor to the same supply voltage, V_CCIO for Arria II GX devices or V_CCPGM for Arria II GZ devices as the USB-Blaster,
EthernetBlaster, EthernetBlaster II, or ByteBlaster II cable.
(2) You only need the pull-up resistors on DATA0 and DCLK if the download cable is the only configuration scheme used on your board. This ensures
that DATA0 and DCLK are not left floating after configuration. For example, if you are also using a configuration device, you do not need the pull-up
resistors on DATA0 and DCLK.
(3) The MSEL pin settings vary for different configuration voltage standards and POR delays. To connect MSEL[3..0]for an Arria II GX device, refer
to Table 9–6 on page 9–9. To connect MSEL[2..0] for an Arria II GZ device, refer to Table 9–7 on page 9–10.
(4) In 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.
