Address Modifier
Configuration
By setting onboard switches, the 1260-00C can specify the state of
the VXIbus Address Modifiers during a VXI master access. During
A16 accesses, the lines AM5, AM4, and AM3 are needed high,
low, and high; and AM1 is needed low. During A24 accesses, the
lines AM5, AM4, and AM3 are all needed high. The 1260-00C
drives the upper three address modifier lines appropriately for
every access. Configure the 1260-00C to drive the lower three
address modifier lines as needed.
Switches S3, S4, and S5 control the AM0, AM1, and AM2 signals.
Figure 3-7 shows the valid settings of S3, S4, and S5.
