EEPROMmemory makes it easier to apply microcontrollers to devices where permanent storage of various parameters is needed (codes for transmitters, motor speed, receiver frequencies, etc.). Low cost, low consumption, easy handling and flexibility make PIC16F84 applicable even in areas where microcontrollers had not previously been considered (example: timer functions, interface replacement in larger systems, coprocessor applications, etc.).

Address bus and Data Bus are seperatewww.technogroovy.com , Cell- +91-7500347448 , +917533940322Address bus and data bus are the sameBy TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-75339403227 8. InHarvard architecture, data bus and address bus are separate. Thus a greater flow of data is possible through the central processing unit, and of course, a greater speed of work. Separating a program from data memory makes it further possible for instructions not to have to be 8-bit words. PIC16F84 uses 14 bits for instructions which allows for all instructions to be one word instructions.www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-75339403228 9. www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-75339403229 10.

Reset is used for putting the microcontroller into a 'known' condition That practically means that microcontroller can behave rather inaccurately under certain undesirable conditions. a) Reset during power on, POR (Power-On Reset) b) Reset during regular work by bringing logical zero to MCLR microcontroller's pin. c) Reset during SLEEP regime d) Reset at watchdog timer (WDT) overflow e) Reset during at WDT overflow during SLEEP work regime.www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-753394032231 32. www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-753394032232 33. www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-753394032233 34. www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-753394032234 35.

Programmemory Program memory has been carried out in FLASHtechnology which makes it possible to program a microcontroller many times before it's installed into a device, and even after its installment if eventual changes in program or process parameters should occur. The size of program memory is 1024 locations with 14 bits width where locations zero and four are reserved for reset and interrupt vector.www.technogroovy.com , Cell- +91-7500347448 , +917533940322By TECNOCRATS INFOTECH www.technogroovy.com , Cell- +917500347448 , +91-753394032238 39. Data memory Data memory consists of EEPROM and RAM memories. EEPROM memory consists of 64 eight bit locations whosecontents is not lost during loosing of power supply. EEPROM is not directly addressable, but is accessed indirectly through EEADR and EEDATA registers. As EEPROM memory usually serves for storing importantparameters (for example, of a given temperature in temperature regulators) , there is a strict procedure for writing in EEPROM which must be followed in order to avoid accidental writing. RAM memory for data occupies space on a memory map fromlocation 0x0C to 0x4F which comes to 68 locations. Locations of RAM memory are also called GPR registers which isan abbreviation for General Purpose Registers. GPR registers can be accessed regardless of which bank is selected at the moment.www.technogroovy.com , Cell- +91-7500347448 , +917533940322www.technogroovy.com , Cell- +917500347448 , +91-753394032239 40. www.technogroovy.com Mail : technogroovy@gmail.com Cell- +91-7500347448 , +91-7533940322www.technogroovy.com , Cell- +91-7500347448 ,www.technogroovy.com , Cell- +91-40
