A.2.3 Selection_Criteria_Keywords
DSTA The instruction will use a short
form if the A register is used as
the destination register.
DSTB The instruction will use a short
form if the B register is used as
the destination register.
SRCA The instruction will use a short
form if the A register is used as
the source register.
SRCB The instruction will use a short
form if the B register is used as
the source register.
A.2.4 Apostrophes The apostrophes in the syntax field are
a notation used for the parser generator and are not put in
the assembler source statement.
