Service request enable register.
Reads service request enable register:
servenabreg = status.request_enable
Writes to system enable register:
status. request_enable = servenabreg
Set servenabreg to one of the following values:

0 Clears all bits.

To set (enables) MSB bit (B0):
status.MEASUREMENT_SUMMARY_BIT
- or - status.MSB

To set (enables) SSB bit (B1): status.SYSTEM_SUMMARY_BIT
- or - status.SSB

To set (enables) EAV bit (B2): status.ERROR_AVAILABLE
- or - status.EAV

To set (enables) QSB bit (B3):
status.QUESTIONABLE_SUMMARY_BIT
- or - status.QSB

To set (enables) MAV bit (B4): status.MESSAGE_AVAILABLE
- or - status.MAV

To set (enables) ESB bit (B5): status.EVENT_SUMMARY_BIT
- or - status.ESB

To set (enables) OSB bit (B7): status.OPERATION_SUMMARY_BIT
- or - status.OSB
servenabreg can also be set to the decimal weight of the bit to be set:
To set bit B0 (MSB), set servenabreg to 1 (20).
To set bit B2 (EAV), set servenabreg to 4 (22).
To set bit B7 (OSB), set servenabreg to 128 (27).
To set more than one bit of the register, set servenabreg to the sum of their decimal
weights. For example, to set bits B0 and B7, set servenabreg to 129 (1 + 128).
