WebCS, CS (chip select) CSN (chip select/enable) CE (chip enable) Operation. The SPI bus can operate with a single master device and with one or more slave devices. If a single slave device is used, the SS pin may be fixed to logic low if the slave permits it. Some slaves require a falling edge of the chip WebOn entering chip select training mode (CSTM), the system drives continuous no-operation (NOP) commands on the bus. CSTM along with NOP commands on the CA bus ensures that no invalid commands are sent to DRAMs. The CS signal sweeps while capturing multiple samples of four continuous CS states, which are clock sampled and evaluated.
