Appendix B

A16 Address Space

Inside the Command

Module or Mainframe

When the A16 address space is inside the Agilent E1405/06 Command

Module (Figure B-2), the module's base address is computed as:

1FC000

+ (LADDR * 40)

2,080,768 + (LADDR * 64)

where 1FC000

(2,080,768) is the starting location of the VXI A16

addresses, LADDR is the module's logical address, and 64 is the number of

address bytes per register-based device. Again, the Agilent E1330's factory

set logical address is 144. If this address is not changed, the module will

have a base address of:

1FC000

+ (90 * 40)

= 1FC000

+ 2400

= 1FE400

2,080,768 + (144 * 64) = 2,080,768 + 9216 = 2,089,984
