Webis defined as the flash clock to out or SPI clock Low to Output Valid, which is represented by a symbol, t V (Clock Low to Output Valid) in Cypress SPI flash datasheets. Table 4 shows the maximum t V values of Cypress SPI flash families in several conditions. A lower t V value results in a higher clock frequency. The other two parameters, T ... WebWhen I monitor the SPI signals I can see CS go low and then I get a 1011 on the Q0 line, and then all zeroes. CCLK runs continuously. The CS signal stays low for about 10 seconds and then appears to tri-state. coolant for beer lines https://obgc.net
