Notes to
(1) Connect the pull-up resistors to the V
(2) Connect the pull-up resistor to the V
(3) 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.
(4) The MSEL pin settings vary for different configuration voltage standards and POR time. You must set the master device in AS mode and the slave
(5) These are dual-purpose I/O pins. The nCSO pin functions as the FLASH_NCE pin in AP mode. The ASDO pin functions as the DATA[1] pin in
(6) Connect the series resistor at the near end of the serial configuration device.
(7) Connect the repeater buffers between the master and slave devices for DATA[0] and DCLK. All I/O inputs must maintain a maximum AC voltage
(8) The 50-Ω series resistors are optional if the 3.3-V configuration voltage standard is applied. For optimal signal integrity, connect these 50-Ω series
