The Motorola M6800 is 40pin DIP IC. It is an 8-bit Microprocessor. It was introduced in 1974 by Motorola. It was designed nearly at the same time when the 8080 was introduced. Like 8080, it also had 16-bit address bus to handle 64KB of data, and 8-bit data bus to ... Read More

We have seen the Internal structure and registers of Motorola M6800 Microprocessor. In this section we will see the addressing modes of M6800.There are six addressing modes in M6800 MPU. These modes are −Immediate Addressing ModeImplied Addressing ModeDirect Addressing ModeExtended Addressing ModeIndexed Addressing ModeRelative Addressing ModeNow Let us see some ... Read More

In Intel 8085 microprocessor I/O and memory operation are differentiated by IO/m` status signal.IO/M` stands for ‘input-output/memory`’. When IO/M` is logic 0, it means that the address sent out by the processor is for addressing a memory location. When IO/M` is logic 1, it means that the address sent out ... Read More

It has eight addressable 8-bit registers: A, B, C, D, E, H, L, F, and two 16-bit registers PC and SP. These registers can be classified as −General Purpose RegistersTemporary Registers: a) Temporary data register b) W and Z registersSpecial Purpose Registers: a)Accumulator b) Flag registers c) Instruction registerSixteen-bit Registers: ...

We have seen some of the features of 8051 microcontrollers. Now in this section, we will discuss different features of it. The 8051 Features are like below8051 has 8-bit Processing Unit to control applications.Using 8051 we can process bits, or in other words, the bit processing capability is present in the ...

Internal RAM of the 8051microcontroller has two parts. First one for register banks, bit addressable memory locations, stacks etc. Another part is the SFR(Special function register) area. Only 21 addresses in the SFR area can be used in this microcontroller. Out of these 21 locations, 11are bit-addressable SFR locations.The bit ... Read More

Were present real numbers in our daily life is not convenient for representing very small numbers, like +0.00000012347650. This same number can be more conveniently represented in scientific notation as +1.23476× 10−07. But this actually stands for +0.000000123476. So there is an error of 0.00000000000005, which forms a very small ... Read More

In 8051 Microcontroller there is 28 different instructions under the Data Transfer Group. In total there are 79 opcodes. The flags are not affected by using the data transfer instructions, but the P (Parity) flag may change if the value of A register is changed using Data Transfer Instruction. Similarly, ... Read More

In 8051 Microcontroller there is 17 different instructions under the Logical Group. In total there are 46 opcodes. These instructions do not affect the flag bits but the CJNE affects the CY flag. In these instructions, the 11-bit address and 16-bit addresses are used.In the following table, we will see ... Read More
