XDRS i Drivers Control
Sets all eight relay drivers according to the binary conversion of i. The binary weight of the
drivers is as follows:
•
Driver 1 = 1
•
Driver 2 = 2
•
Driver 3 = 4
•
Driver 4 = 8
•
Driver 5 = 16
•
Driver 6 = 32
•
Driver 7 = 64
•
Driver 8 = 128
Add together the weights of the drivers to be activated, and send the total. For example, when
i = 255, all eight relay drivers are turned on.
SRE i SQR Mask
Writes a decimal number to the SRQ mask register (see the Status Reporting and Service
Request Control section). Setting a bit to 1 generates an SRQ interrupt when the
corresponding bit in the status register changes from 0 to 1.
CSB Clear Status Byte
Resets the status byte.
CLR Clear Device
Clears the SRQ mask register and the status register.
