Notes to Figure 13–7:
(1) Connect these pull-up resistors to 3.3-V supply.
(2) The nCEO pin can be left unconnected or used as a user I/O pin when it does not feed other device’s nCE pin.
(3) Power up the ByteBlaster II or USB Blaster cable’s V_CC with a 3.3-V supply.
You can use the Quartus II software with the APU and the appropriate
configuration device programming adapter to program serial
configuration devices. All serial configuration devices are offered in an
8-pin or 16-pin small outline integrated circuit (SOIC) package and can be
programmed using the PLMSEPC-8 adapter.
