It is a simple way of connecting objects and communication between them.How does delegate work?A delegate is created with help of protocol. A protocol is declared in class, inside which some event will happen, that should notify other classes. In protocol we write the declaration of function and it is defined inside the calling class.How to create a delegate?We’ll do this with help of an example project.Steps to perform −Create a class, name it ...

In this section, we will see the basic architecture of the Motorola M6800 Microprocessor, and different registers to write programs into it.To write programs we have to care about the registers and some instructions to access them during program execution. So from this diagram, we can see that there are two 8-bit Accumulators A and B, some 16-bit registers (Program Counter PC, Index Register IX, Stack Pointer SP), and 8-bit flag register CCR.Both of the Accumulators Aand B have the same prominence in the Instruction set. There are very few instructions in 6800, where the Accumulator A is used but B ... 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 basic syntax of M6800 Assembly Language Programming.If a number is 8CH in hexadecimal, then we have to use $ sign before it. So it will be $8C. A number without $ is treated as decimal number. Similarly, an immediate data is denoted by # symbol. #50FF is a data, but ... Read More

In this section, we will see the different types of instructions of Motorola M6800 microprocessor. There are 72 different types of instructions and 197 different opcodes. So there are 51 1-Byte instruction, 103 2-Byte instruction and 43 3-Byte instruction.As we know that the Intel 8085 has 246 opcodes, though 6800 is more powerful than 8085. The Z-80 has 700 instructions but M6800 has some more advanced branching instructions.The different instruction groups are like these −Data Transfer GroupArithmetic GroupLogical GroupBranch GroupMiscellaneous InstructionsData transfer GroupIn this group, there are 14 instructions. We can find 38 opcodes for these 14 instructions. These instructions ... Read More

In Motorola M6800, there are two hardware interrupt pins. These pins are NMI and. IRQ  These pins are active low input pins. The first one is non-maskable and the second one is maskable and lower priority interrupt. When the IM flag is 1, or CCR register is set, the interrupt is masked or disabled.When the Micro processor enters into some Interrupt Service Subroutine (ISS), it uses SEI instruction to mask the interrupt even if the IRQ activated. The reverse action can be performed using the CLI instruction. It can unmask the interrupt.When in the interrupt is occurred, the M6800 follows ... Read More
