IEEE-488.2 Command Reference 14
U8480 Series Programming Guide 343
*SRE <NRf>
The *SRE <NRf> command sets the Service Request Enable register bits. This
register contains a mask value for the bits to be enabled in the Status Byte
Register. A 1 in the Enable Register enables the corresponding bit in the Status
Byte Register; a 0 disables the bit. The parameter value, when rounded to an
integer and expressed in base 2, represents bit 0 to bit 7 of the Service Request
Enable Register. Table 14-3 shows the contents of this register. Refer to the
Status Block Diagram at the end of Chapter 10, "STATus Subsystem" for further
information.
