6.24. SEG(7'Segment) 变换为7’Segment 值

6.24. SEG(7'Segment):变换为7’Segment 值

 

标记
Relay组合
因数	src: 原本(source) Relay(或数字) dst: 目的地(destination) Relay
说明	Rung处于激活状态、将src的值变换为7’Segment 值(8bit)后保存于dst。 Dst为Word(W)形式、就把2个7’Segment 值(8bit)保存于 dst。

使用例	SEG(XB3、RW3): 相当于XB3值的7’Segment 值保存于RW3。 如果(XB3)=(&H17)、 就把结合上述SEGD_1(SEGM_B|SEGM_C=0x02|0x04=0x06)=&H06和 上述SEGD_7(SEGM_A|SEGM_B|SEGM_C=0x01|0x02|0x04=0x07)=&H07的&H0607保存于 RW3。
