AR1:AR0 or AR3:AR2 or AR5:AR4 auxiliary registers
Push the contents of two 16-bit auxiliary registers (ARn and ARm) onto the
stack pointed to by SP.
Post-increment SP by 2:
PUSH AR1:AR0
[SP] = AR0;
[SP+1] = AR1;
SP += 2;
PUSH AR3:AR2
[SP] = AR2;
[SP+1] = AR3;
SP += 2;
PUSH AR5:AR4
[SP] = AR4;
[SP+1] = AR5;
SP += 2;

This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
