A16 Address Space
Inside the Command
Module or Mainframe
Appendix B
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)
16
2,080,768 + (LADDR * 64)
where 1FC000
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)
16
2,080,768 + (144 * 64) = 2,080,768 + 9216 = 2,089,984
