A single register controls all the outputs. The signal gives the instruction to control the output of TPL9202. The NCS signal enables the SCLK and MOSI data when it is low. After NCS is set to low for T1, synchronization clock and data begin to transmit and, after the 8-bit data has been transmitted, NCS is set high again to disable SCLK and MOSI and to transfer the serial data to the control register. SCLK must be held low when NCS is high. Figure 1. Serial Communications 8 Submit Documentation Feedback Copyright © 2006–2008, Texas Instruments Incorporated Product Folder Link(s): TPL9202 |
