PIC16F887 Microcontroller is an 8-bit microcontroller designed with RSIC CPU technology, which helps the microcontroller to give the maximum output using less power. It has a total of 40-pins and all these pins come in multiple packages to solve the requirement of small and modern circuits.
What is Clrwdt?
Clear Watchdog Timer CLRWDT instruction resets the Watchdog Timer. It also resets the prescaler of the WDT. Status bits, TO and PD, are set.
What is a 16f690?
PIC16F690 is an 8-bit PIC microcontroller, developed by Microchip, that comes with 20-pin interface. Operating voltage is identical to other controllers in the PIC community and ranges from 2 to 5.5 V. Program memory and RAM memory is 7K and 256 bytes respectively.
What is significance of D 0 bit in Addwf F D?
ADDWF – Add W and f Syntax: [label] ADDWF f, d Description: Add the contents of the W and f registers. If d = w or d = 0 the result is stored in the W register.
What are the features of PIC microcontroller?
PIC devices generally feature:
- Flash memory (program memory, programmed using MPLAB devices)
- SRAM (data memory)
- EEPROM memory (programmable at run-time)
- Sleep mode (power savings)
- Watchdog timer.
- Various crystal or RC oscillator configurations, or an external clock.
Which functions are set through configuration word in pic16f877a?

- Clock Source.
- Watchdog Timer.
- Power-up Timer.
- Brown-out Reset.
- Low-Voltage (Single-Supply)
- Data EEPROM Memory Code Protection.
- Flash Program Memory Write.
- In-Circuit Debugger Mode.
What is WDT reset?
“A watchdog timer (WDT) is a hardware timer that automatically generates a system reset if the main program neglects to periodically service it. It is often used to automatically reset an embedded device that hangs because of a software or hardware fault.” ().
What is the use of WDT?
A watchdog timer (WDT) is a timer that monitors microcontroller (MCU) programs to see if they are out of control or have stopped operating. It acts as a “watchdog” watching over MCU operation. A microcontroller (MCU) is a compact processor for controlling electronic devices.
What is BSF and BCF?
BSF is the inversing operation of BCF. This is also a bitwise operation. The BSF instruction will set the specified bit in the f register (simply called Bit Set Flag or Bit Set command).
What is the difference between PIC and Arduino?
The PIC is a micro-controller. The Arduino is a code base designed to run on a controller like the PIC or AVR, that abstracts the low level coding required to utilize the features and peripherals of the micro-controller. You could say the PIC is the hardware, and Arduino is like an OS running on the hardware.
What is PIC microcontroller used for?
PIC microcontrollers are used in different new applications such as smartphones, audio accessories, and advanced medical devices. There are many PICs available in the market ranging from PIC16F84 to PIC16C84. These types of PICs are affordable flash PICs.
