SYNC frequency is MCLK/32 with a phase delay of tCSP ns . W.A.R.P. stores the data present on input buses at the rising edge of MCLK, returns a SYNC pulse after tCSP ns indicating that is waiting for new data and address that must be given within next 31MCLK pulses. Afterwards W.A.R.P. stores the data on input buses and restores a new SYNC pulse. W.A.R.P. stores the data situated in I0-I7 and the addresses A0-A9 into its internal registers. Figure 8.
