    State Control bits with a state event trigger behave like a ’state’ that is forced upon the DDA pump. CIM 200/500 will attempt to make the pump operate according to the ’requested’ state in the control registers 00101-00103. Due to certain state/mode restrictions, this might not always be possible (see explanation of the bit in question).
