Service Request Enable Register (Sre) - LeCroy PXA125 User Manual

Service Request
Enable Register
(SRE)
Programming Reference 4-84
The Service Request enable register is an 8-bit register that enables
corresponding summary messages in the Status Byte Register. Thus,
the application programmer can select reasons for the generator to
issue a service request by altering the contents of the Service
Request Enable Register.
The Service Request Enable Register is read with the *SRE?
common query. The response to this query is a number that
represents the sum of the binary-weighted value of the Service
Request Enable Register. The value of the unused bit 6 is always
zero.
The Service Request Enable Register is written using the *SRE
command followed by a decimal value representing the bit values of
the Register. A bit value of 1 indicates an enabled condition.
Consequently, a bit value of zero indicates a disabled condition. The
Service Request Enable Register is cleared by sending *SRE0. The
generator always ignores the value of bit 6. Summary of *SRE
commands is given in the following.
*SRE0 - Clears all bits in the register.
*SRE1 - Not used.
*SRE2 - Not used.
*SRE4 - Not used.
*SRE8 - Not used.
*SRE16 - Service request on MAV.
*SRE32 - Service request on ESB summary bit.
*SRE128 - Not used.
