The family of microcontrollers are bithowever they do have some bit operations. From Wikipedia, the free encyclopedia. Ford created the Ford Microelectronics facility in Colorado Springs in to propagate the EEC-IV family, develop microcontoller custom circuits for use in automobiles, and to explore the gallium arsenide integrated circuit market.
Retrieved 22 August WordPress Embed Customize Embed. The serial port has several modes and its own baud rate generator. When Timer 1 is over flown ,the interrupt bit is enabled or disabled.
Diode circuits are provided on the chip itself ,which gives self protection. The four modes of the serial port are referred to as modes 0, 1, 2 and 3.
Parts in that family included thewhich incorporated a memory controller allowing it to address a megabyte of memory.
Timers and Counters in Microcontroller. Later the, and were added to the family.
This CAM file stores up to 8 commands. This bit WDT is a counter which is incremented every state time. Individual interrupts can be enabled or disabled by setting or clearing the bits in the Interrupt mask register.
All registers are 16 bit or 17 bit wide. In order to view it, please contact the author of the presentation. Operating Modes of Automatically changes to Flash or non-Flash embed. Contd … When the hardware detects one of the 8 interruptsit sets the corresponding bit in the interrupt pending register.
The Microcontroller Architecture Block Diagram functional units can be divided into two major sections:. Instruction and Data Format of The serial port is similar to that on the controller.
Graw -hill International Ed. The serial port is configured in four modes. The memory controller provides the addresses for the internal ROM and external memory.
It can monitor four independently configurable HSI lines and capture the value of Timer 1 when an event takes place.
Your email address will not be published. Features of Microcontroller.
There are 4 lines HIS. In addition to these functional units, there are some sections which support overall operation of the chip such as the clock imcrocontroller and baud rate generator.
Instruction Set of Microprocessor. The block diagram is shown in the next slide. Each output line require a pullup resistor of about 15K. Contd … The chip has a baud rate generator which is independent of Mcrocontroller 1 and Timer 2, so using the serial port does not take away any of the HSI, HSO or timer flexibility or functionality. Features of Programmable Interrupt Controller. Any of the locations in the register file can be used for sources or destinations for most of the instructions.
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 microconrtoller.
The performs most of the calculations in RALU. All these interrupts are enabled or disabled using the 9 th bit of PSW register. Executing Assembly Language Program. It consists of several functional units, namely.
