WebSetup Time For a Start Condition (t SU;STA ): is a timing specification that is only taken into account during a repeated start condition. It is the minimum time the SDA line is required to remain high before initiating a repeated start. Websynchronous, the timing is related to the system clock (SK) (Figure 7). For example, if a COPS controller outputs a value at the falling edge of the clock and is latched in by the peripheral device at the rising edge, then the following rela-tionship has to be satisfied: tDELAY a tSETUP s tCK where tCK is the time from data output starts to ...

Spi timing spec

WebSPI Timing The SPI has four modes of operation, 0 through 3. These modes essentially control the way data is clocked in or out of an SPI device. The configuration is done by two bits in the SPI control register (SPCR). The clock polarity is specified by the CPOL control bit, which selects an active high or active low clock. WebBelow are timing examples for each of the 4 data transfer sizes in the SDP-B SPI protocol. Note the wait times after the CS goes active and the wain times between successive bursts of 8 or 16 bit data in the 24 and 32bit transfers cannot be guaranteed but are included to give a rough estimate of the timing specifications for the SPI interface on the SDP.
