VXI:WRITe

:WRITe VXI:WRITe < logical_addr> ,< register_addr> ,< data> allows access to the entire 64 byte A16 register address space for the device specified by logical_addr. Since the VXIbus system is byte-addressed, while the registers are 16 bits wide, registers are specified by even addresses only. This method of identifying registers follows the VXIbus standard format.

Parameters	Parameter	Parameter	Range of	Default
	Name	Type	Values	Units
	logical_addr	decimal	Must round to 0 through 255	none
		numeric
	register_addr	numeric	must round to an even value	none
			from 0 through 62 (3E h)
	data	numeric	must round to -32768 to 32767	none
			(0 to FFFFh)
Comments	• Specifying an odd register address will cause an error 2003,"Invalid word
	address".

•Specifying a logical address not currently in use in the system will cause an error 2005,"No card at logical address".

•L ogical_addr must be specified in decimal. Register_addr and data may be specified in decimal, hex (# H), octal (# Q), or binary (# B).

•This command has been retained for compatibility with existing programs. For new programs you should use the VXI:REG:WRIT command.

•Accesses are 16-bit non-privileged data accesses.

•Related Commands: VXI:READ?, VXI:REG:WRIT
