Functional Description

Data transfers into the diagnostic register occur on the

LOW-to-HIGH transition of DCLK. Mode and SDI determine

what data source will be loaded. The pipeline register is

loaded on the LOW-to-HIGH transition of PCLK. Mode se-

lects whether the data source is the data input or the diag-

nostic register output. Because of the independence of the

clock inputs, data can be shifted in the diagnostic register via

DCLK and loaded into the pipeline register from the data in-

put via PCLK simultaneously, as long as no setup or hold

times are violated. This simultaneous operation is legal.
