;                                                                             *
;   This file is a basic template for creating Assembly code for a dsPIC 30F  *
;   device.  Copy this file into your project directory and modify or         *
;   add to it as needed.                                                      *
;                                                                             *
;   Add the device linker script (e.g., p30f6010.gld) and the device          *
;   include file (e.g. p30f6010.inc). If you are using this file for          *
;   an application that uses a device other than dsPIC 30F6010 which is       *
;   identified in the list of supported devices, add the linker script and    *
;   include file specific to that device into your project.                   *
;                                                                             *
;   This template file makes use of a run-time start-up module which is       *
;    included in the run-time library, "libpic30.a" file. This file is        *
;   present in the "pic30_tools\lib\" folder. If you do not want to use the   *
;   run-time library, then use the template file, "tmp6010.s", provided in    *
;   this folder.                                                              *
;                                                                             *
;   Refer to the document "dsPIC 30F Assembler, Linker and Utilities User's   *
;   Guide" for further information on the functions of the start-up module    *
;   in the run-time library.                                                  *

;   If interrupts are not used, all code presented for that interrupt         *
;   can be removed or commented out using comment symbols (semi-colons).      *

;    Notes:                                                                   *
;    ======                                                                   *
;                                                                             *
;1. The device include file defines bit names and their location within SFR   *
;   words. Replace the path to the include file, if necessary.                *
;   For e.g., to use the p30f2010 device modify the .include directive to     *
;   .include "Yourpath\p30F2010.inc"                                          *
;                                                                             *
;2. The "config" macro is present in the device specific '.inc' file and can  *
;   be used to set configuration bits for the dsPIC 30F device.               *
;   The '.inc' files also contain examples on using the "config" macro.       *
;   Some examples have been provided in this file. The user application may   *
;   require a different setting for the configuration bits.                   *
;   The dsPIC 30F 16-bit MCU Family Refernce Manual(DS70046) explains the     *
;   function of the configuration bits.                                       *
;                                                                             *
;3. The "_main" label is used as the first label in the code section. This    *
;   helps invoke the start-up module in the run-time library "libpic30.a".    *
;   The start-up module contains routines that help initialize the stack      *
;   pointer, .data, .ndata, .xdata and .ydata sections. For more information  *
;   on the functions present in the start-up module, refer to the document    *
;   "dsPIC 30F Assembler, Linker and Utilities User's Guide".                 *
;                                                                             *
;4. A ".section <section_name>, <attributes>" directive declares a new section*
;   named "<section_name>" with an attribute list that specifies if the       *
;   section is located in Program Space(code), Uninitialized(bss) or          *
;   Initialized Data Space(data). Refer to the document "dsPIC 30F Assembler, *
;   Linker and Utilities User's Guide" for further details.                   *
;                                                                             *
;5. Initialize W registers: Using uninitialized W registers as Effective      *
;   Addresses(pointers) will cause an "Uninitialized W Register Trap" !       *
;                                                                             *
;6. The label "__T1Interrupt" is defined in the device linker script. The     *
;   label defines the starting location in program space of the Timer1        *
;   interrupt service routine (ISR).                                          *
;   Similarly, the linker script defines labels for all ISRs. Notice, that    *
;   the ISR label names are preceded by two underscore characters.            *
;   When users needs to write ISR code, they must use these labels after      *
;   providing them global scope. The linker will then place the ISR address in*
;   the respective interrupt vector table location in program space.          *
;   Context Save/Restore in ISRs can be performed using the double-word PUSH  *
;   instruction,PUSH.D. User can also make use of MOV.D, PUSH and PUSH.S      *
;   instructions. Refer dsPIC 30F 16-bit MCU Family Refernce Manual(DS70046)  *
;   for further details.                                                      *
;                                                                             *
