1. Fill in the blanks (1) For the decimal number 36, its binary number is 111, its hex number is 【2】, and its BCD number is 【3】. (2) If the binary number is 1010 0101, then its 1's complement is 【4), the 2's complement is 【5】. (3) The ASCII code for '5' is [61, the ASCII code for character 'B' is_【7】. (4) In microcomputer there are three types of buses, they are [81,data bus, and [191. (5) If CS=2500H, DS=3200H, SS=4300H, IP=2200H, SP-3000H, the physical address of the next instruction to be executed is 【10】 and the logical address of current stack top is 【1】 (6) For instruction MOV AX, [BX+6], the addressing modes of source operand is 【121, and the addressing modes of destination operand is 【13】. (7) For CPU 8088, when 16-bit data is pushed onto the stack, the stack pointer SP is [14], (increased by 2, decreased by 2) but when 16-bit data is popped off the stack, the stack pointer SP is 【15】 .(increased by 2, decreased by 2) (8) After the instructions MOV AX, 2500H and ADD AX, 2300H have been executed in sequence, find the status of SF= [16], AF= [17] and ZF= 【18). (9) In PC/XT, 8088CPU uses 【19】 (how many) clock cycles for memory reading or writing. In read timing, the control signal ALE is sent out by 8288 in the 【20】 clock cycle.
