Example
PUSH @T ; Push the contents of XT(31:15) into
; the location pointed to by
; SP. Post-increment SP by 1
PUSH @AL ; Push the contents of AL onto into
; the location pointed to by
; SP. Post-increment SP by 1
PUSH @AR4 ; Push the lower 16-bits of XAR4 into
; the location pointed to by
; SP. Post-increment SP by 1
PUSH *XAR4++ ; Push the value pointed to by XAR4
; into the location pointed to
; by SP. Post-increment SP and XAR4
