1、单片机程序__________________________________________________1、编程将片内RAM30H单元开始的１５B的数据传送到片外RAM3000H开始的单元中去。解：STRAT：MOVR0,#30HMOVR7,#0FHMOVDPTR,#3000HLOOP：MOVA,@R0MOVX@DPTR,AINCR0INCDPTRDJNZR7,LOOPRET2、编程将片内RAM40H单元中的内容送到片外RAM2000H单元中。解：ORG0100HMOVA，40HMOVDPTR，#2000HMOVX@DPTR，AEND___________________________
2、_________________________________________________________________________3、将内部RAM40H开始的10个字节的数搬到外部RAM2000H处MOVDPTR,#2000HMOVR0,#40HMOVR2,#0AHLOOP:MOVA,@R0MOVX@DPTR,AINCR0INCDPTRDJNZR2,LOOPSJMP$END4、将存于外部RAM8000H开始的50H数据传送0010H的区域，请编程实现。MOVDPTR，#8000HMOVR0，#10HMOVR2，#50HLOOP：MOVXA，@DPTR；取数MOVX@R0,A；存
3、数1NCDPTR1NCR0DJNZR2，LOOPRET________________________________________________________________________________________________________________________________________________________________________________________________________5．片内RAM40H开始的单元内有10B二进制数，编程找出其中最大值并存于50H单元中．解START:MOVR0,#40H;数据块首地址送R0MO
4、VR7,#09H;比较次数送Ｒ７ MOVA,@R0;取数送ＡLOOP:INCR0MOV30H,@R0;取数送３０HCJNEA,30H,NEHT;（A）与（30H）相比NEXT:JNCBIE1(A)≥(30H)转BIR1MOVA,30H;(A)＜(30H),大数送A BIE1:DJNZR7,LOOP;比较次数减1，不为0，继续比较 MOV50H,A;比较结束，大数送50H RET6.片内RAM30H开始的单元中有10B的二进制数，请编程求它们之和（和＜256）．___________________________________________________________
5、_________________________________________解 ADDIO：MOVR0,30HMOVR7,#9MOVA,@R0LOOP：INCR0ADDA,@R0DJNZR7,LOOPMOV30H,ARET____________________________________________________________________________________________________7、设从内存BLOCK单元开始存放一无符号数的数据块，其长度为LEN。试找出其最小数，并存入MIN单元。COMP：MOVA，#0FFH；置比较的初始值MOVR2，#LEN；
6、置数据块长度____________________________________________________________________________________________________MOVR1，#BLOCK；置地址指针LOOP：CLRCSUBBA，@R1；比较JCNEXT；若小，则恢复原值MOVA，@R1SJMPNEXT1NEXT：ADDA，@R1NEXT1：INCR1；若大，则取下个数比较DJNZ：DJNZR2，LOOPMOVMN，A；存最小数SJMP$8、比较存放在ONE,TWO,TRE三个单元的无符号数，并将小数存放在20H单元中。MOVA,ONECJNEA
7、,TWO,RRRR:JCSSMOVA,TWOCJNEA,TRE,TTTT:JCWWSJMPUUSS:CJNEA,TRE,VVVV:JCWWUU:MOVA,TREWW:MOV20H,A____________________________________________________________________________________________________9、设在单片机内部
