I have an ALFAT-USB, The File System user manual says to see the “device specifications” for details on how to select “the specific device dependent pins” for the interface. The only specifications I can find are on page 1 of the schematic. The title box of the schematic says there are two pages, but only one downloads. How do I get the second page where I might find the answers to my questions?
I identify a pin labeled “SPI_SSEL” but I do not see similar pins for UART or I2C. Please explain.
Regarding the pin labeled “VBat” - where do I find the specifications for this input?
How do use the “wakeup” pin?
