Notes to
(1) Connect the pull-up resistors to the V
(2) The nCEO pin is left unconnected or used as a user I/O pin when it does not feed the nCE pin of another device.
(3) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL[3..0], refer to
(4) The AP configuration ignores the WAIT signal during configuration mode. However, if you are accessing flash during user mode with user logic,
(5) When cascading Cyclone IV E devices in a multi-device AP configuration, connect the repeater buffers between the master device and slave
(6) The other master device must fit the maximum overshoot equation outlined in
(7) The other master device can control the AP configuration bus by driving the nCE to high with an output high on the I/O pin.
(8) The other master device can pulse nCONFIG if it is under system control and not tied to V
