Bits 0-1: RESERVED -
Bit 2: MaxFlowLimitEnabled
Indicates if the MaxFlowLimit is enabled (enable with register 00101, bit 5).
Only available on MAGNA3 and MGE model H.
0: Disabled
1: Enabled.
Bit 3: ResetAlarmAck
Indicates if a ResetAlarm command was acknowledged by the device. This bit will be set
when the CIU has accepted a ResetAlarm command, and the programmer can clear the
ResetAlarm bit. The ResetAlarmAck bit will automatically be cleared to 0 by the CIU when
the ResetAlarm bit is cleared by the master device, and a new ResetAlarm command can
be attempted by raising ResetAlarm bit again.

Bit 7: Direction
Indicates the current rotational direction of the E-pump.

Open loop
Percentage of E-pump performance.
Common examples
4700: 47 %
