Registers and Queues That Affect the Status Byte
Registers that affect the bits of the status byte are shown below.
Standard event register Sets bit 5 (ESB) of the status byte to 1 or 0.
Output queue Sets bit 4 (MAV) of the status byte to 1 or 0.
Extended event register Sets bit 3 (EES) of the status byte to 1 or 0.
Error queue Sets bit 2 (EAV) of the status byte to 1 or 0.
Enable Registers
Registers that are used to mask a bit so that the bit will not affect the status byte even
when it is set to 1, are shown below.
Status byte Mask the bits using the service request enable register.
Standard event register Mask the bits using the standard event enable register.
Extended event register Mask the bits using the extended event enable register.
Writing/Reading from Registers
The *ESE command is used to set the bits in the standard event register to 1’s or 0’s.
The *ESE? command is used to query whether the bits in the standard event register are
1’s or 0’s. For details regarding these commands, see chapter 5.
