For two-operand 8-bit operations, the other operand can be either an immediate value, another 8-bit register, or a memory cell adtasheet by the bit register pair HL.

Intel C orp ora tion assumes no re sponsib ility fo r the use o f any circu itry oth er than c irc 855 itry em bodied in an Intel. One sophisticated instruction is XTHL, which is used for exchanging the register pair HL with the value stored at the address indicated by the stack pointer.

The only 8-bit ALU operations that can have a destination other than the accumulator are the unary incrementation or decrementation instructions, which can operate on any 8-bit register or on memory addressed by HL, as for two-operand 8-bit operations.

The inputs are ihtel latched because the CPU only has to read their current values, then store the data in a CPU register or memory if it needs to be referenced at a later time. It is a large and heavy desktop box, about a 20″ cube in the Intel corporate blue color which includes a CPU, monitor, and a single 8-inch floppy disk drive.


The zero flag is set if the result of the operation was 0.

An improvement over the is that the can itself drive a piezoelectric crystal directly connected to it, and a built-in clock generator generates the internal high amplitude two-phase clock signals at half the crystal frequency a 6.

Figure 3 shows the timing.

State signals are provided by dedicated bus control signal pins and two dedicated bus state ID pins named S0 and S1. This mode is selected when D 7 bit of the Control Word Register is 1.

Some instructions use HL as a limited bit accumulator. Kntel parity flag is set according to the parity odd or even of the accumulator.

When the Intel bus control interface is selected, this signal acts as the WR signal. Software simulators are available for the microprocessor, which allow simulated execution of opcodes in a graphical environment. This unit uses the Multibus card cage which was intended just for the development system.

These are intended to be supplied by external hardware in order to invoke a corresponding interrupt-service routine, but are also often employed as fast system calls. Although the is an 8-bit processor, it has some bit operations.

The later iPDS is a portable unit, about 8″ x 16″ x 20″, with a handle. The is supplied in a pin DIP package. On thethisDatashewt 9.

All interrupts are enabled by the EI instruction and disabled by the DI instruction. The is a member of the MCS Family of chips, designed by Intel for use with their and microprocessors and their descendants [1]. An Intel AH processor. As an example, consider an input device connected to at port A. It can also accept a second processor, allowing a limited form of multi-processor operation where both processors run simultaneously and independently.

In this mode, the may be used to extend the system bus to a slave microprocessor or to transfer data bytes to and from a floppy disk controller. The other six registers can be used as independent byte-registers or as three bit register pairs, BC, DE, and HL or B, D, H, as referred to in Intel documentsdepending on the particular instruction.

Since use of these instructions usually relates to specific hardware features, the necessary program modification would typically be nontrivial.
