TAP Operation
The user must be aware that the TAP controller clock can only operate at a frequency up to 50 MHz, while
the RLDRAM clock operates much faster. As a consequence, it is possible that an input or output will
undergo a transition right at the moment when the TAP takes the snapshot in the Capture-DR state of the
SAMPLE/PRELOAD instruction. The TAP may then try to capture a signal while in transition (metastable
state). This will not harm the device, but there is no guarantee as to the value that will be captured. To
guarantee that the boundary scan register will capture the correct value of a signal, the signal must meet the
TAP's setup and hold time ( tCS plus tCH) around the rising edge of TCK.
