XARn XAR0 to XAR7, 32-bit auxiliary registers
Description Load the contents of the 32-bit addressed location with the contents of
XARn:
[loc32] = XARn;
Flags and
Modes
N If (loc32 = @ACC), then the load to ACC is tested for a negative condition.
Bit-31 of the ACC register is the sign bit, 0 for positive, 1 for negative. The
negative flag bit is set if the operation on the ACC register generates a
negative value, otherwise it is cleared.
Z If (loc32 = @ACC), then the load to ACC is tested for a zero condition. The bit
is set if the result of the operation on the ACC register generates a 0 value,
otherwise it is cleared
Repeat This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
MOVL @ACC, XAR0 ; Move the 32-bit contents of XAR0 into ACC.
; If bit 31 of the ACC is 1 set N. If
; ACC = 0, set Z.
MOVL *XAR1, XAR7 ; Move the 32-bit contents of XAR7 into the
; location pointed to by XAR1.
MOVL *XAR6++,XAR6 ; Move the 32-bit contents of XAR6 into the
; location pointed to by XAR6. Post-increment
; the contents of XAR6.
MOVL *−−XAR5,XAR5 ; Predecrement the contents of XAR5. Move the
; 32-bit contents of XAR5 into the location
; pointed to by ; XAR5.
