There is a PUSH instruction macro, described in Section 8.5, "Multiple
Value Pushes," on page 8-19, that can be used with the POP instruction
presented here.
Table 6-7 lists the move instructions.

Due to instruction pipelining, if an AGU register (Rn, SP, or M01) is
directly changed with a move instruction, the new contents may not be
available for use until the second following instruction. See the restrictions
discussed in Section 4.4, "Pipeline Dependencies," on page 4-33.

Program Control Instructions

The program control instructions include branches, jumps, conditional branches, conditional jumps, and
other instructions that affect the program counter and software stack. Program control instructions may
affect the status register bits as specified in the instruction. Also included in this instruction group are the
STOP and WAIT instructions that can place the DSP chip in a low-power state. See Section 8.1.1, "Jumps
and Branches," on page 8-2 and Section 8.11, "Jumps and JSRs Using a Register Value," on page 8-33 for
additional jump and branch instructions that can be synthesized from existing DSP56800 instructions.
Table 6-8 lists the program control instructions.
