Register Definitions
The A24 RegistersThe following A24 registers are accessible at the base address defined by the device’s offset Register. The registers at offsets 0 to E16 are not accessible using longword (D32) accesses. The registers at offsets 1016 to FFFFF16 may be accessed by any of the of the D08(EO), D16, or D32 modes.
FFFFF16 | Movable DSP |
8000 016 | Bus Window |
7FFFF16 | Fixed DSP |
3000 016 | Bus Window |
2FFFF16 | Send/Receive |
2000 016 | Data Registers |
1FFFF16 | Fixed DSP |
0004 F16 | Bus Window |
0003 F16 | VXI Bus A16 |
0000 016 | Registers |
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.
