Power-up conditions
When the power supply is turned on, V
time, the Chip Select (S) line is not allowed to float but should follow the V
therefore recommended to connect the S line to V
Figure 3: Bus master and memory devices on the SPI
In addition, the Chip Select (S) input offers a built-in safety feature, as the S input is edge
sensitive as well as level sensitive: after power-up, the device does not become selected
until a falling edge has first been detected on Chip Select (S). This ensures that Chip Select
(S) must have been high, prior to going low to start the first operation.
