LOCAL-BUS的错误描述是（）
A: LOCAL-BUS-A用于主架，LOCAL-BUS-B用于E架
B: 621型机架的C5、C6为LOCAL-BUS的扩展接口，不用时要终止
C: 1024型机架只有C5接口，说明C5接口是LOCAL-BUS-B的接口
D: LOCAL-BUS是一对时分总线，每个TRU单元只占用其中3个TS

举一反三
- We are ________ a survey to find out what our customers think of their local bus service.
- Local train and bus times are ______ on the notice board. A: displayed B: expressed C: made up D: noted down
- Local train and bus times are ______ on the notice board. A: displayed B: expressed C: made up D: muted down
- Verilog HDL中，下面语句的正确解释是：（）assign bus [7:4] = {bus [0], bus [1], bus[2], bus[3] } ; A: bus[0]、bus[1]、bus[2]、bus[3]分别赋值给bus[4]、bus[5]、bus[6]、bus[7] B: bus[0]、bus[1]、bus[2]、bus[3]分别赋值给bus[7]、bus[6]、bus[5]、bus[4] C: bus[0]、bus[1]、bus[2]和bus[3]的值保持不变 D: bus[0]、bus[1]、bus[2]和bus[3]的值均变为二进制0
- In Verilog HDL, which option is the correct interpretation of the following statement? assign bus [7:4] = {bus [0], bus [1], bus[2], bus[3] } ; A: bus[0], bus[1], bus[2] and bus[3] are assigned to bus[4], bus[5], bus[6] and bus[7] respectively B: bus[0], bus[1], bus[2] and bus[3] are assigned to bus[7], bus[6], bus[5] and bus[4] respectively C: The values of bus[0], bus[1], bus[2] and bus[3] remain unchanged D: All the values of bus[0], bus[1], bus[2] and bus[3] become binary 0
