Always write zeroes to this field.
Define auto-refresh to occur at next burst or next cmd boundary.
Sets the mode for when the automatic refresh will occur. If the auto_refresh_mode parameter is set and a
refresh is required to memory, the EMI will delay this refresh until the end of the current transaction (if the
transaction is fully contained inside a single page), or until the current transaction hits the end of the current
page.
'b0 = Issue refresh on the next DRAM burst boundary, even if the current command is not complete.
'b1 = Issue refresh on the next command boundary.
Always write zeroes to this field.
Trigger auto-refresh at boundary specified by AUTO_REFRESH_MODE. WRITE-ONLY
Initiates an automatic refresh to the DRAM devices based on the setting of the auto_refresh_mode parameter.
If there are any open banks when this parameter is set, the EMI will automatically close these banks before
issuing the auto-refresh command. This parameter will always read back as 0x0.
'b0 = No action
'b1 = Issue refresh to the DRAM devices
Always write zeroes to this field.
