A.3.4
Some instructions support a parallel move or dual parallel read in conjunction with some other operation.
These instructions encode the source and destination registers for the parallel move or dual parallel read
separately from the registers that are used in the core operations. This section presents the encoding fields
that are used to specify the registers that are accessed in the parallel move portion of the instruction.
Instructions with a single parallel move of the forms “X:<ea_m>,GGG” and “GGG,X:<ea_m>” encode the
source or destination register using the values given in Table A-14 on page A-329.
A-328
1.This encoding is only used for 32-bit stack push and pop operations.
