MOVB AX.LSB, loc16
6-191
Repeat This instruction is not repeatable. If this instruction follows the RPT
instruction, it resets the repeat counter (RPTC) and executes only once.
Example
; Swap the byte order in the 32-bit ”Var32” location.
; Before operation: Var32 = B3 | B2 | B1 | B0
; After operation: Var32 = B0 | B1 | B2 | B3
MOVL XAR2,#Var32 ; Load XAR2 with address of ”Var32”
MOVB AL.LSB,*+XAR2[3] ; ACC(B0) = Var32(B3), ACC(B1) = 0
MOVB AH.LSB,*+XAR2[1] ; ACC(B2) = Var32(B1), ACC(B3) = 0
MOVB AL.MSB,*+XAR2[2] ; ACC(B1) = Var32(B2), ACC(B1) = unch
MOVB AH.MSB,*+XAR2[0] ; ACC(B3) = Var32(B0), ACC(B1) = unch
MOVL @Var32,ACC ; Store swapped result in ”Var32”
