3–2 SROM Mini-Debugger Command Set
Command Summary
• All stores are followed with two MB instructions. This keeps writes ordered
(from the system’s point of view) and prevents merging in the write queue. For
more information on the MB instruction, see the CPU’s hardware reference
manual.
• For commands that use an address range, the ending address is not included in
the range. The last read or store is performed in the immediately preceding
quadword or longword, depending on the state of the qw data flag.
3.3 Command Summary
Table 3–1 summarizes the command set for the Alpha Microprocessors SROM
