HP VXI E1432A - Manual (Page 173)

The HP E1432A VXI Registers
The HP E1432A 16 Channel 51.2 kSa/s Digitizer plus DSP is a
register-based VXI device. Unlike message-based devices which use
higher-level programming using ASCII characters, register-based devices are
programmed at a very low level using binary information. The greatest
advantage of this is speed. Register-based devices communicate at the level
of direct hardware manipulation and this can lead to much greater system
throughput.
Users do not need to access the registers in order to use the HP E1432A.
The HP E1432A’s functions can be more easily accessed using the
HP E1432A Host Interface Library software. However this chapter
describing the registers is provided for your information.
The A16 Registers
The following A16 registers are accessible at the base address defined by
the device’s logical address. The register at offsets 00
$ to E $ are not
accessible using longword (D32) accesses. The registers at offsets 10 $ to
3E $ may be accessed by any of the D08(EO), D16, or D32 modes. All of
these registers are also accessible at the device A24 base address.
