[1] Parameters are valid over operating temperature range unless otherwise specified.
[2] Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply voltages.
Remark: Note that the signal names SCK, MISO, and MOSI correspond to signals on
pins SPI_SCK, SPI_MOSI, and SPI_MISO in the following SPI timing diagram.
