In addition to the above constants, questionableRegister can be set to the numeric equivalent of
the bit to set. To set more than one bit of the register, set questionableRegister to the sum of
their decimal weights. For example, to set bits B12 and B13, set questionableRegister to 12,288
(which is the sum of 4,096 + 8,192).

Example 1
questionableRegister = status.questionable.S1INL
+
status.questionable.S6INL
status.questionable.enable = questionableRegister
Uses constants to set bits B1 and B6 of
the status questionable enable register.
Example 2
-- decimal 66 = binary 0100 0010
questionableRegister = 66
status.questionable.enable = questionableRegister
Uses a decimal value to set bits B1 and
B6 of the status questionable enable
register.

Usage
requestSRQEnableRegister = status.request_enable
status.request_enable = requestSRQEnableRegister
requestSRQEnableRegister
The status of the service request (SRQ) enable register; a zero (0)
indicates no bits set (also send 0 to clear all bits); other values indicate
various bit settings
