单片机复位后,SP、PC、I/O口(P0、P1、P2、P3)的内容为( )
A: A. SP = 00H PC = 1000H I/O口= FFH
B: B. SP = 00H PC = 0000H I/O口= 00H
C: C. SP = 07H PC = 0000H I/O口= FFH
D: D. SP = 07H PC = 0000H I/O口= 00H
A: A. SP = 00H PC = 1000H I/O口= FFH
B: B. SP = 00H PC = 0000H I/O口= 00H
C: C. SP = 07H PC = 0000H I/O口= FFH
D: D. SP = 07H PC = 0000H I/O口= 00H
举一反三
- 单片机复位后,SP、PC、I/O口(P0、P1、P2、P3)的内容为( ) A: A. SP = 00H PC = 1000H I/O口= FFH B: B. SP = 00H PC = 0000H I/O口= 00H C: C. SP = 07H PC = 0000H I/O口= FFH D: D. SP = 07H PC = 0000H I/O口= 00H
- 51单片机复位后,PC与P口(i/o)的值为: 0000H,00H|0000H,FFH|0003H,00H|0003H,FFH
- 51单片机复位后,PC与P0口(I/O)的值为()。 A: 0000H,00H B: 0000H,FFH C: 0003H,FFH D: 0003H,00H
- 单片机复位后,SP、PC、I/O口(P0、P1、P2、P3)的内容为( )
- MCS-51单片机复位后,程序计数器PC、 堆栈指针SP、端口寄存器P0 -P3、 数据指针DPTR分别为: A: 0000H,00H,00H,0000H B: xxxxH,xxH,xxH,xxxxH C: 0000H,07H,00H,0000H D: 0000H,07H,FFH,0000H
