The A24 Registers
The following A24 registers are accessible at the base address defined by the device’s offset Register. The registers at offsets 0 to E16are not accessible using longword (D32) accesses. The registers at offsets 1016to FFFFF16may be accessed by any of the of the D08(EO), D16, or D32 modes.

Registers
The A24 registers are defined as follows:
VXI Bus A16 Registers: These are the same registers accessed at the device’s A16 base address.
Fixed DSP Bus Window: Accesses to this region are mapped to the corresponding locations at the base of the internal DSP’s memory map, also accessible through Page 0 of the moveable DSP bus window.
Send/Receive Data Registers: Accesses to any address in this region will read/write the Send and Receive Data registers defined in the A16 register set. VME Bus D32 Block Transfers are supported for these addresses only.
Movable DSP Bus Window: Accesses to this region are mapped (by the Page Map register) to different 512 kB regions of the internal DSP bus.
