A separate incrementor is used for the Program Counter. Both of them have open drain outputs. 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. The four modes of the serial port are referred to as modes 0, 1, 2 and 3.
This is a high performance 16 bit microcontroller with register to register architecture. Input Output Transfer Techniques.
The reset pin is a bidirectional line with a strong internal pullup. WordPress Embed Customize Embed. 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. These two modes are commonly used for interprocessor communication Contd…: If any of the port 1 pin is to be used as input port the corresponding pin must be made high by writing the data 1 PowerPoint Presentation: Seven Segment Display Interfacing.
In order to view it, microcotnroller contact the author of the presentation. InIntel announced the discontinuance of the entire MCS family of microcontrollers. When Timer 1 is over flown ,the interrupt bit is enabled or disabled Contd This counter is cleared by program after periodic interval and not allowed to overflow.
Features of Microcontroller.
Unit 7 : FEATURE OF / MICROCONTROLLER – svaltaf51
Diode circuits are provided on the chip itself ,which gives self protection. The weak internal pullup is designed to be overridden by the external device which drives the line. This page was last edited on 15 Augustat Contd … These addressing modes increase the flexibility and overall execution speed of controller.
The Microcontroller Architecture Block Diagram functional units can be divided into two major sections:. Presentation Description Introduction to Microcontrollers. The serial port is configured in four modes. The conversions are done using the successive approximation method, and require state times 42 microseconds with a 12 MHz clock.
In addition to these functional units, there are some sections which support overall operation of the chip such as the clock generator and baud rate generator.
PORT 1 This is a quasi bidirectional port which can be used either as input or as the out port. The chip is automatically reset when the Vdd deviates from the prescribed levels. T his line may also be driven by internal watchdog timer also. The also had on-chip program memory lacking in the The difference between the two is, that in Mode 2 the serial port interrupt will not be activated unless the ninth data bit is a one; in Mode 3 the interrupt is activated whenever a byte is received.
Your email address will not be published. This is a byte wide register which is loaded sequentially with two bytes, and internally stores the value as a word.
True digital to analog converters are difficult to make on a microcontroller because of all of the digital noise and the necessity of providing an on chip, relatively high current, rail to rail driver. All these interrupts are enabled or disabled using the 9 th bit of PSW register.
They are Immediate addressing mode Register direct addressing mode Indirect addressing mode Microcontroller with auto increment mode Short indexed mode and Long indexed mode.
By writing 1 to any line it can be micrpcontroller as an input and other lines can serve as output lines. They are Immediate addressing mode Register direct addressing mode Indirect addressing mode Indirect with auto increment mode Short indexed mode and Long indexed mode Contd…: The serial port has several modes and its own baud rate generator.
