36 / 159 page  M7040N 36/159 – Cycle 2: The host ASIC drives the DQ[71:0] with thedatatobewritten to thedataarray or mask array location of the selected device. The M7040N writes the data from the DQ[71:0] Bus only to the subfield that has the corresponding mask bit set to '1' in the global mask register specified by the index {CMD[10], CMD[5:3]} and supplied in Cycle 1. – Cycles 3 to n + 1: The host ASIC drives the DQ[71:0] with the data to be written to the next data array or mask array location (addressed by the auto-increment ADR field of the WBURREG register) of the selected device. The M7040N writes the data on the DQ[71:0] Bus only to the subfield that has the correspond- ing mask bit set to '1' in the global mask register specified by the index {CMD[10], CMD[5:3]} and supplied in Cycle 1. The M7040N drives the EOT signal low from Cycle 3 to Cycle n; the M7040N drives the EOT signal high in Cycle n + 1(nis specified in theBLENfield of theWBUR- REG). – Cycle n + 2: The M7040N drives the EOT signal low. At the termination of the Cycle n + 2, the M7040N floats the EOT signal to a 3-state, and a new instruction can begin. Figure 20.
