The VT1433B VXI Registers

The VT1433B 8-Channel 196 kSamples/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 VT1433B. The VT1433B’s functions can be more easily accessed using the VT1432A Host Interface Library software (which is used for both the VT1433B and the VT1432A 16 Channel 51.2 kSamples/s Digitizer plus DSP). However this chapter describing the registers is provided as supplemental 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 0016 to E16 are not accessible using longword (D32) accesses. The registers at offsets 1016 to 3E16 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.
