Cycle 2:
The host ASIC drives the DQ[71:0]
with the data to be written to the data array 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 (n is specified in the BLEN field of the WBUR-
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.
