FIGURE 28: Write-Mode-Control Pseudo-Transfer Timing  
NOTES:  
NOTE G: The write-mode-control cycle is used to change the SDQs from the output mode to the input mode. This allows serial data to be written  
into the data register. This figure assumes that the device was originally in the serial-read mode.
