PIC16F84A temel assembly kod şablonu.

PIC16F84A için hazırlanmış kod şeması aşağıdaki gibidir. Bu şema sayesinde kendi kodlarınızı daha rahat oluşturabilirsiniz. 
;****************************************************
;   This file is a basic code template for assembly code generation   *
;   on the PICmicro PIC16F84A. This file contains the basic code      *
;   building blocks to build upon.                                    *
;                                                                     *
;   If interrupts are not used all code presented between the ORG     *
;   0x004 directive and the label main can be removed. In addition    *
;   the variable assignments for 'w_temp' and 'status_temp' can       *
;   be removed.                                                       *
;                                                                     *
;   Refer to the MPASM User's Guide for additional information on     *
;   features of the assembler (Document DS33014).                     *
;                                                                     *
;   Refer to the respective PICmicro data sheet for additional        *
;   information on the instruction set.                               *
;                                                                     *
;   Template file assembled with MPLAB V4.00.00 and MPASM V2.20.12.   *

__CONFIG   _CP_OFF & _WDT_ON & _PWRTE_ON & _RC_OSC

; '__CONFIG' directive is used to embed configuration data within .asm file.
; The lables following the directive are located in the respective .inc file.
; See respective data sheet for additional information on configuration word.
