Since a detailed description of the instruction set will take up a very large number of pages, the description of instructions in this section is limited to that which is necessary for the reader to appreciate
ECE 447: MSP430 Status Register (SR) V - Overflow, set when a result of a signed operation has overflowed. N - Negative, set to the msb of the result which indicates a negative number if the values are signed. Z - Zero, set when the result is 0. C - Carry, set to indicate an ...
Slightly later, Intel produced the 8008 microprocessor. Both chips copied the Datapoint 2200's instruction set architecture with minor changes. The Intel 8008 chip in its 18-pin package. The small number of pins hampered the performance of the 8008, but Intel was hesitant to even go to the...
A String Instruction in 8086 is a series of the same type of data items in sequential memory locations. The CMPS instruction can be used to compare a byte in one string with a byte in another string or to compare a word in one string with a word in another string. SI is used to ho...
V-bit :V-bit decides the number of shifts for rotate and shift instructions. If V = 0, then count = 1; if V = 1, the count is in CL register. For example, if V = 1 and CL = 2 thenshiftor rotate instruction shifts or rotates 2-bits ...
