WebSep 2, 2024 · NSS output disable (SSOE = 0). If the MCU is master, this allows multimaster capability. If NSS is pulled low, SPI enters master mode fault state and the device is automatically reconfigured in slave mode. In slave mode, the NSS pin works as a standard "chip select" input and the slave is selected while the NSS line is at low level. 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. how much are bitters bottles worthWebOct 10, 2024 · Chip Select (CS) Chip select is used if more than 1 ADC module is used.
