(1)
Connect these pull-up resistors to 3.3-V supply.
(2)
Power up the ByteBlaster II cable's VCC with a 3.3-V supply.

If using an EPCS4 device, MSEL[3..0] should be set to 1101. Refer to
Table 7–11for more details.
You can program serial configuration devices with the Quartus II
software with the Altera programming hardware (APU) and the
appropriate configuration device programming adapter. The EPCS1 and
EPCS4 devices are offered in an eight-pin small outline integrated circuit
(SOIC) package.
In production environments, serial configuration devices can be
programmed using multiple methods. Altera programming hardware or
other third-party programming hardware can be used to program blank
serial configuration devices before they are mounted onto printed circuit
boards (PCBs). Alternatively, you can use an on-board microprocessor to
program the serial configuration device in-system using C-based
software drivers provided by Altera.
