Example 1
requestSRQEnableRegister = status.MSB + status.OSB
status.request_enable = requestSRQEnableRegister
Uses constants to set the MSB and OSB bits of the service request (SRQ) enable register.
Example 2
-- decimal 129 = binary 10000001
requestSRQEnableRegister = 129
status.request_enable = requestSRQEnableRegister
Uses a decimal value to set the MSB and OSB bits of the service request (SRQ) enable register.

requestSRQEventRegister = status.request_event
requestSRQEventRegister
The status of the request event register; a zero (0) indicates no
bits set; other values indicate various bit settings
Details
This attribute is used to read the service request event register, which is returned as a numeric value.
Reading this register returns a value. The binary equivalent of the value of this attribute indicates
which register bits are set. In the binary equivalent, the least significant bit is bit B0, and the most
significant bit is bit B7. For example, if a value of 1.29000e+02 (which is 129) is read as the value of
this register, the binary equivalent is 1000 0001. This value indicates that bit B0 and bit B7 are set.
