Hence this is called a register to register architecture. Howeverif the program does not progress properly by any reason such as Electrostatic Discharge ESD or due to any hardware related problems ,the overflow occurs.

It consists of several functional units, namely. CS1 Russian-language sources ru Wikipedia articles needing clarification from March Articles containing Russian-language text.

Each command specifies the action time,the nature of the action ,whether an interrupt is to occur and whether Timer 1 or Timer 2 is the reference Timer. If it is to be serviced ,the CPU pushes the contents of the program counter on to the stack and and reloads it with the vector corresponding to the desired interrupt. They also take up a fair amount of silicon area which can be better used for other features.

All other locations can be used either for microcontfoller or for data storage or for memory mapped peripherals. PORT 1 This is a quasi bidirectional port microcontrolled can be used either as input or as the out port. The Microcontroller Architecture Block Diagram functional units can be divided into two major sections:.


It is mapped It is mapped at the memory address 0FH. The HIS unit can store upto 8 entries Timer 1 values.

This includes a radiation-hardened device with a Spacewire interface under the designation VE7T Russian: Differences between the and the include the memory interface bus, the ‘s M-Bus being a ‘burst-mode’ bus requiring a tracking program counter in the memory devices.

Intel MCS-96

Later the, and were added to the family. From Wikipedia, the free encyclopedia.

The frequency is fixed at a period of 64 microseconds for a 12 MHz clock speed. Contd … PowerPoint Presentation: The presentation is successfully added In Your Favorites. In addition to these functional units, there are some sections which support overall operation microcontrooler the chip such as the clock generator and baud rate generator. Retrieved 22 August The 20 sources vector through 8 locations or interrupt vectors.

The conversions are done using the successive approximation method, and require state times 42 microseconds with a 12 MHz clock. Diode circuits are provided on the chip itself ,which gives self protection.

Each instruction uses at least one microconttroller the addressing modes.

If this bit is set to 1 all the interrupts are enabled and disabled when reset to zero. The serial port is configured in four modes. It has one synchronous and three asynchronous modes. The A to D converter does use a D to A, but the currents micrrocontroller are very small.


These two modes are microcintroller used for interprocessor communication. This register can be read or modified as a byte register. The block diagram is shown in the next slide. This is a high performance 16 bit microcontroller with register to register architecture. The family is often referred to as the 8xC family, orthe most popular MCU in the family. Input Output Transfer Techniques.

The least significant byte is loaded to the register followed by the most significant. The main features of the MCS family include a large on-chip microcontrollrr, Register-to-register architecturethree operand instructions, bus controller to allow 8 or 16 bit bus widths, and direct flat addressability of large blocks or more of registers.


These two modes are commonly used for interprocessor communication Contd…: Each output line require a pullup resistor of about 15K. The indirect auto increment mode ,increments a word address by one after a byte operation and two after a word operation. Contd … These addressing modes increase the flexibility and overall execution speed of controller.

Although MCS is thought of as the 8x family, the was the first member of the family. The INTEL microcontroller is provided with on chip self protection circuitaryto protect the chip from large currents. InIntel announced the discontinuance of the entire MCS family of microcontrollers.
