General term for the equipment used to communicate with a computer CPU; or the data involved in that communication.
After a SEP R4 instruction is executed, the following events take place: A built-in memory pointer register is used to indicate the memory location for the DMA cycles. Finally, the two most significant bytes are added together with the carry datashet the preceding addition. They can be tested by CDP instructions to determine whether or not they are active. C onstru ction of the clock circuit is simplified by use of XTAL input. It is considered an “illegal” code and should not be used. During the S3 cycle, the current values of the X and P registers arc stored in the T register.
Each bit of the subtrahend is complemented, and the resultant byte plus 1 datasheer added to the minuend. This instruction can be used to compare two bytes for equality since identicaJ values will result in all zeros in D.
Dataheet to “MAIN” program. In this example, a subroutine is called by loading its address into a register and using “SEP register” to do the call.
A minor change to this program could have it outputting the cx4076 between the two dagasheet, an indication per- haps of the degree of mechanical “error.
It describes the microprocessor architecture and provides dagasheet set of simple, easy-to-use programming instructions. For example, the instruction “30” followed by “45” will execute an unconditional branch to the address 45 on the current page; the instruction “FC” followed by “22” will exe- cute an immediate add operation in which the operand 22 is added to the second operand from the D register.
It util- izes the COS? As many subroutines in succession as are required may be called. A negative-going MWK pulse will cause the data byte to be written into the addressed memory location. Next, the two most significant bytes are added using the ADC instruction. Data may be considered as: Then, a pseudo program is nothing more than a series of ad- dresses-the low-bylc address of each successive sub- routine to be executed.

This instruction is equivalent to FD with the operands reversed. Denote end of string with null Other methods for passing parameters to a subroutine involve the use of a register, a memory area pointed to by a register, a reserved area of memory, DF, or Q. Or, he may want to shut off interrupts during a critical part of the main program.
It can then perform specified arith- metic operations using the stored numbers and transfer the results to an output display or printing device. MAC architecture, any one of the bit scratch-pad registers can be used as a program counter. To avoid the dangerous practices referred to above, but still to need have only one copy of such a routine present in memory, the programmer should use the concept of a subroutine.
The rate at which machine cycles occur is, therefore, one eighth of the clock frequency.

Two 4-bit hex digits contained in each instruction byte datqsheet designated as I and N, as shown in Fig. NO and a read level on MRD will enable data from the bus into output register 1 while the input register 1 is disabled from the bus. These operations are Mvided into eight genera!
Load the address of subroutine ‘SUB1″ into R 7: The 8-bit result will be stored in the D register, and the 1-bit Cd406 which represents the borrow will be set to I if there is no borrow out datssheet to 6 if there is a borrow out from the most significant bit.
The state of the KM and MRD lines determines whether a byte is to be read from the addressed memory location, written into it, or neither operation performed.

Latching all eight A. This simple, unique architecture results in datashdet number of system advantages. If an exter nal osc illator is used, no connection is required at the XfAL terminal. This operation is used to specify which scratch-pad “agister is to be used as the program counter. Load number of datsheet PLO R6. During the next machine cycle executethe CPU generates a non-memory cycle and the memory output is Timing Diagrams: Executing 74 or 7C allows a carry-in from a previous addition, thus facilitating multibyte addition.
To describe or interpret the byte on the bus, the decoded outputs of the three N bits are used. The current contents of R 6 is pushed dagasheet the stack. When DMA-lN is asserted, a byte on the data bus from an external device is written into memory at the location specified by the register R 0: It shows, line for line, how the assembler interpreted the assembly language program.
