What I/O devices can be added to the MCS-48?
Standard MCS-80/85 type I/O devices may be added to the MCS-48 using the same bus and timing used for Data Memory expansion. I/O devices reside on the Data Memory bus and in the data memory address space and are accessed with the same MOVX instructions.
What is this MCS-48 document for?
This document came into existence as the effort to collect and maintain the information about the MCS-48 microcontroller family I have access to. The collected paperwork consists of several copied sheets from Intel databooks that age over time, slowly fading away.
What is the use of [SP] in 8086?
SAHF Copy flag register to top of stack. [SP] [SP] – 2 [ [SP]] [Flags] Eg. PUSHF Copy word at top of stack to flag register. [Flags] [ [SP]] The 8086 provides many arithmetic operations: addition, subtraction, negation, multiplication and comparing two values. The add instruction adds the contents of the source operand to the destination operand.
How many parameters are required for string manipulation in 8086?
The 8086 supports a set of more powerful instructions for string manipulations for referring to a string, two parameters are required. I. Starting and End Address of the String. II. Length of the String. The length of the string is usually stored as count in the CX register.
What are the different assembly language directives?
The following directives are commonly used in the assembly language programming practice using Microsoft Macro Assembler (MASM) or Turbo Assembler (TASM). ü DB: Define Byte The DB directive is used to reserve byte or bytes of memory locations in the available memory.
