Guaranteed by design and characterization, not subject to production test.
Falling or rising edge as determined by the control bits of the serial word. Strong or weak SDO driver selected via the control register.
Daisy-chain and readback modes cannot operate at maximum clock frequency. SDO timing specifications measured with a load circuit, as shown in Figure 5.
