Notes to
(1) Connect these 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) Power up the V
(4) The MSEL pin settings vary for different configuration voltage standards and POR time. To connect MSEL[3..0], refer to
(5) These are dual-purpose I/O pins. This nCSO pin functions as the FLASH_NCE pin in AP mode. The ASDO pin functions as the DATA[1] pin in
