Readback_Option*
This Client Side parameter enables the user
to configure the timing of a read after a
write. The Readback operation will apply to
all drivers that support Active Reads and
Write-Through operations.
Readback_Asynchronously: When a write
occurs, the read will occur when scheduled
Readback_On_Write: When a write occurs,
set the timer to 0, so the Responsible Map
Descriptor will get queued in the next cycle
Readback_Immediately_On_Write: Prioritize
both write and read to happen in a higher
priority queue than normal reads. The
Readback operation will apply to all drivers
that support Active Reads and Write-
Through operation
Readback_Asynchronously,
Readback_On_Write
,
Readback_Immediately_On_Write
