* DINT | 禁用(通用)中断 | |
句法 | DINT | |
操作 | 0 → GIE 或 (0FFF7h .AND.SR → SR/.NOT. src .AND. dst → dst) | |
仿真 | BIC #8,SR | |
说明 | 所有中断被禁用。 常数 08h 被按位取反,然后与 SR 进行逻辑与运算。结果被放置在 SR 内。 | |
状态位 | 状态位不受影响。 | |
模式位 | GIE 被清零。OSCOFF 和 CPUOFF 不受影响。 | |
示例 | SR 中的通用中断启用 (GIE) 位被清零来实现一个 32 位计数器的非中断移动。这就确保任一中断进行移动期间计数器不会被修改。 |
DINT ; All interrupt events using the GIE bit are disabled
NOP
MOV COUNTHI,R5 ; Copy counter
MOV COUNTLO,R6
EINT ; All interrupt events using the GIE bit are enabled
禁用中断
如果保护任一代码序列不被中断,在不可中断序列开始前,DINT 应该至少在一个指令上被执行,或者在它之后应该有一个 NOP 指令。
