Instruction Set Description

4.6.4.8 MOVA

MOVA Move the 20-bit source to the 20-bit destination

MOVA Rsrc,Rdst

Syntax

MOVA #imm20,Rdst

MOVA z16(Rsrc),Rdst

MOVA EDE,Rdst

MOVA &abs20,Rdst

MOVA @Rsrc,Rdst

MOVA @Rsrc+,Rdst

MOVA Rsrc,z16(Rdst)

MOVA Rsrc,&abs20

Operation src → Rdst

Rsrc → dst

Description The 20-bit source operand is moved to the 20-bit destination. The source operand is not

affected. The previous content of the destination is lost.

Status Bits N: Not affected

Z: Not affected

C: Not affected

V: Not affected

Mode Bits OSCOFF, CPUOFF, and GIE are not affected.

Examples Copy 20-bit value in R9 to R8

MOVA R9,R8 ; R9 -> R8

Write 20-bit immediate value 12345h to R12

MOVA #12345h,R12 ; 12345h -> R12

Copy 20-bit value addressed by (R9 + 100h) to R8. Source operand in addresses (R9 +

100h) LSBs and (R9 + 102h) MSBs.

MOVA 100h(R9),R8 ; Index: + 32 K. 2 words transferred

Move 20-bit value in 20-bit absolute addresses EDE (LSBs) and EDE+2 (MSBs) to R12

MOVA &EDE,R12 ; &EDE -> R12. 2 words transferred

Move 20-bit value in 20-bit addresses EDE (LSBs) and EDE+2 (MSBs) to R12. PC

index ± 32 K.

MOVA EDE,R12 ; EDE -> R12. 2 words transferred

Copy 20-bit value R9 points to (20 bit address) to R8. Source operand in addresses

@R9 LSBs and @(R9 + 2) MSBs.

MOVA @R9,R8 ; @R9 -> R8. 2 words transferred
