JMP | 无条件跳转 | |
句法 | JMP label | |
操作 | PC +(2 × 偏移)→ PC | |
说明 | 包含在指令中的带符号 10 位字偏移被乘以 2,符号被扩展,并且被加入到 20 位 PC 中。这意味着相对于全部存储器范围内的 PC 的 -511 至 +512 字的无条件跳转。JMP 指令在其相对于 PC 的有限范围内可被用作一个 BR 或者 BRA 指令。 | |
状态位 | 状态位不受影响 | |
模式位 | OSCOFF,CPUOFF 和 GIE 不受影响。 | |
示例 | 字节 STATUS 被设置为 10。然后进行到标签 MAINLOOP 的跳转。低 64KB 内的数据,完全存储器范围内的程序。 |
MOV.B #10,&STATUS ; Set STATUS to 10
JMP MAINLOOP ; Go to main loop
示例 | Timer_A3 的中断矢量 TAIV 被读取并用于程序流程。完全存储器范围内的程序,但是中断处理器一直在低 64KB 内启动。 |
ADD &TAIV,PC ; Add Timer_A interrupt vector to PC
RETI ; No Timer_A interrupt pending
JMP IHCCR1 ; Timer block 1 caused interrupt
JMP IHCCR2 ; Timer block 2 caused interrupt
RETI ; No legal interrupt, return
