read-only mode nor to any of the SPI Base modes. However, for the SPI Extended
mode (read only) and the SPI Base mode (both read only and read/write), the nCS
signal and SCK are not allowed to toggle at the same time.

ALTUFM_SPI megafunction is under the Memory Compiler folder on page 2a of the
MegaWizard Plug-In Manager. On page 3, you can choose whether to implement the
Read/Write or Read Only mode as the access mode for the UFM. You can also select
the configuration mode (Base or Extended) for SPI on this page. You can specify the
initial content of the UFM block on page of the ALTUFM MegaWizard Plug-In
Manager as discussed in
The UFM block’s internal oscillator is always running when the ALTUFM_SPI
megafunction is instantiated for read/write interface. The UFM block’s internal
oscillator is disabled when the ALTUFM_SPI megafunction is instantiated for read
only interface.
