TLV2556 Timing_01_CFGR2_Config_SBAS739.gif

NOTE:

To minimize errors caused by noise at CS, the internal circuitry waits for a set-up time after the CS falling edge before responding to control input signals. Therefore, no attempt should be made to clock in an address until the minimum CS setup time has elapsed.
Figure 1. Timing for CFGR2 Configuration

The host must configure CFGR2 before valid device conversions can begin. This can be accessed through command 1111. This can be done using eight, twelve, or sixteen I/O CLOCK clocks. (A minimum of eight is required to fully program CFGR2.)

After CFGR2 is configured, the following cycle configures CFGR1 and a valid sample or conversion is performed. CS can be held low for each remaining cycle. First valid conversion output data is available on the third cycle after power up.
