16-Channel Relay Multiplexer Registers
Register
Addressing
Register addresses for register-based devices are located in the upper 25%
of VXI A16 address space. Every VXI device (up to 256 devices) is
allocated a 64 byte (32 word) block of addresses. The Multiplexer uses six
of the 64 addresses allocated.
Figure B-1 shows the register address location within A16. Figure B-2
shows the location of A16 address space in the E1300/01 Mainframe and
E1405/06 Command Module.
