*SRE (Service Request Enable)
*SRE (Service Request Enable)
The *SRE command sets the bits in the Service Request Enable Register. The
Service Request Enable Register contains a mask value for the bits to be
enabled in the Status Byte Register. A bit set to one (1) in the Service Request
Enable Register enables the corresponding bit in the Status Byte Register. A
zero (0) disables the bit. Table 4-3 lists the bits in the Service Request Enable
Register and what they mask.
The Service Request Enable Register is cleared at power-on. The *RST and
*CLS commands do not change the register.
The *SRE query returns the value of the Service Request Enable Register.
