the difference between 16f877 and 16f877A as follows (as far as i know) : i) 16f877A is an improved version of 16f877 with additional built-in comparator function. ii) programmer that supports 16f877 might not support 16f877A.

What does F mean in pic18f?

The F part stands for Flash, denoting that the device uses Flash memory, to mark them out from the PICxxC range, which are non-Flash.

What is the meaning of F in pic16f877a?

The F in a name generally indicates the PICmicro uses flash memory and can be erased electronically. Conversely, a C generally means it can only be erased by exposing the die to ultraviolet light (which is only possible if a windowed package style is used).

What is the meaning of Tblrd plus?

TBLRD*+ — Table Read with post-increment.

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 PIC18F4520 microcontroller?

The PIC18F4520-I/P is an Enhanced Flash Microcontroller with 10-bit A/D and nanoWatt technology. The PIC18F4520 device include an internal oscillator block which generates two different clock signals, either can be used as the microcontroller’s clock source.

What does Movlw mean?

Move Literal Value Into W
The MOVLW means ‘Move Literal Value Into W’, which in English means put the value that follows directly into the W register.

What is Addwf?

1) ADDLW. “ADDLW” instruction is used for performing addition operation (adding a constant with W register). By using this instruction, we can add two bits easily and the result value can be stored in another register or memory location. Syntax: Label ADDLW k.
