This is the minimum time the user must wait between SPI commands. 3. This is the minimum time the user must wait before bringing EN up. 4. This is the minimum time the user must wait to send a SRR command between consecutive frames. If Tsrr time is not met the SRR request is ignored. Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the Electrical Characteristics if operated under different conditions. |
