The outputs remain valid for a minimum of t
leading edge of CLK. This allow the data to be latched into circuits with
non-zero hold time requirements.

clock.
Length Select.
The length select input is used to determine the register
delay of the TMC2111A. This input is registered and affects the output t
after the clock edge after it is input to the device (see Timing Diagram).
Delay lengths are specified in Table 1.
All inputs and outputs are synchronous and operate from a
