The A16 base address used in register-based programming depends on
whether the A16 address space is located inside the E1300(01)
Mainframe/E1405/E1406 Command Module or elsewhere (e.g. embedded
computer). Figures C-1A, C-1B, and Table C-1 enable you to determine the
base address for the following computer configurations:
•
E1300/E1301 Instrument BASIC (IBASIC)
•
External Computer over HP-IB to E1300/E1301 Mainframe or
E1405/E1406 Command Module
•
V/360 Embedded Controller (C-Size system)

When using DIAG:PEEK? and DIAG:POKE, the width (number of bits) is 8 or 16.
