Configuration Features
Figure 9–11. AP Configuration with Multiple Bus Masters
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 III devices in a multi-device AP configuration, connect the repeater buffers between the master device and slave devices
(6) The other master device must fit the maximum overshoot equation outlined in
(7) The other master device can pulse nCONFIG if it is under system control rather than tied to V

you can optionally use the normal I/O to monitor the WAIT signal from the Numonyx P30 or P33 flash.
for DATA[15..0] and DCLK. All I/O inputs must maintain a maximum AC voltage of 4.1 V. The output resistance of the repeater buffers must
fit the maximum overshoot equation outlined in
