ANDX.A | 源地址字与目的地址字的逻辑与 | ||
ANDX.[W] | 源字与目的字的逻辑与 (AND) | ||
ANDX.B | 源字节与目的字节的逻辑 AND | ||
语法 | ANDX.A src,dst | ||
ANDX src,dst 或 ANDX.W src,dst | |||
ANDX.B src,dst | |||
操作 | src .and. dst → dst | ||
说明 | 源操作数和目的操作数被逻辑与。结果被放置在目的操作数中。源操作数不受影响。两个操作数都位于完全地址空间内。 | ||
状态位 | N: | 如果结果为负 (MSB=1),则置 1,如果为正 (MSB=0),则复位 | |
Z: | 如果结果为零,则置 1;否则复位 | ||
C: | 如果结果不为零,则置 1;否则复位。C=(.not.Z) | ||
V: | 复位 | ||
模式位 | OSCOFF,CPUOFF 和 GIE 不受影响。 | ||
示例 | R5(20 位数据)中置 1 的位被用作一个针对两个字内地址字 TOM 的掩码 (AAA55h)。如果结果为零,一个分支指令被指向标签 TONI。 |
MOVA #AAA55h,R5 ; Load 20-bit mask to R5
ANDX.A R5,TOM ; TOM .and.R5 -> TOM
JZ TONI ; Jump if result 0
... ; Result > 0
或更短: |
ANDX.A #AAA55h,TOM ; TOM .and.AAA55h -> TOM
JZ TONI ; Jump if result 0
示例 | 由 R5(20 位地址)指向的一个表格字节被与 R6 逻辑与。R6.19:8 = 0.表格指针自动加 1。 |
ANDX.B @R5+,R6 ; AND table byte with R6.R5 + 1
