Motorola MVME162 Offset Registers, Relative addresses are limited to 1MB 5 digits, regardless

Using the 162Bug Debugger

Note

In commands with RANGE specified as ADDR DEL ADDR, and with size option W or L chosen, data at the second (ending) address is acted on only if the second address is a proper boundary for a word or longword, respectively.

Offset Registers

4			Eight pseudo-registers (R0 through R7) called offset registers are used to
			simplify the debugging of relocatable and position-independent modules. The
			listing files in these types of programs usually start at an address (normally 0)
			that is not the one at which they are loaded, so it is harder to correlate
			addresses in the listing with addresses in the loaded program. The offset
			registers solve this problem by taking into account this difference and forcing
			the display of addresses in a relative address+offset format. Offset registers
			have adjustable ranges and may even have overlapping ranges. The range for
			each offset register is set by two addresses: base and top. Specifying the base
			and top addresses for an offset register sets its range. In the event that an
			address falls in two or more offset registers’ ranges, the one that yields the least
			offset is chosen.
				Relative addresses are limited to 1MB (5 digits), regardless
	N	ote
