= Don’t care. Signal can be high or low during this time.

A. All XINTF accesses (lead period) begin on the rising edge of XCLKOUT. When necessary, the device will insert an alignment cycle

before an access to meet this requirement.

B. During alignment cycles, all signals will transition to their inactive state.

C. During inactive cycles, the XINTF address bus will always hold the last address put out on the bus. This includes alignment cycles.

D. For each sample, setup time from the beginning of the access can be calculated as: D = (XWRLEAD + XWRACTIVE + n – 1) tc(XTIM) –

tsu(XRDYsynchL)XCOHL where n is the sample number (n = 1, 2, 3 and so forth).

E. Reference for the first sample is with respect to this point E = (XWRLEAD + XWRACTIVE) tc(XTIM)
