When this bit is set to 1, an internal attention is
generated when an error occurs.
This bit controls whether the Send BD Initiator
state machine is active or not. When set to 0, it
completes the current operation and cleanly
halts.
Until it is completely halted, it remains 1 when
read.
When this is set to 1, the Send BD Initiator State
machine is reset.
This is a self clearing bit.
