/***********************************************************************
* This file is a basic template for creating C code for a dsPIC30F *
* device. Copy this file into your project directory and modify or *
* add to it as needed. *
* Add the suitable linker script (e.g., p30f6010.gld) to the project. *
* *
* If interrupts are not used, all code presented for that interrupt *
* can be removed or commented out with C-style comment declarations. *
* *
* For additional information about dsPIC architecture and language *
* tools, refer to the following documents: *

* Other Comments: *
* *
* 1) C attributes, designated by the __attribute__ keyword, provide a *
* means to specify various characteristics of a variable or *
* function, such as where a particular variable should be placed *
* in memory, whether the variable should be aligned to a certain *
* address boundary, whether a function is an Interrupt Service *
* Routine (ISR), etc. If no special characteristics need to be *
* specified for a variable or function, then attributes are not *
* required. For more information about attributes, refer to the *
* C30 User's Guide. *
* *
* 2) The __space__(xmemory) and __space__(ymemory) attributes are *
* used to place a variable in X data space and Y data space, *
* respectively. Variables accessed by dual-source DSP instructions *
* must be defined using these attributes. *
* *
* 3) The aligned(k) attribute, used in variable definitions, is used *
* to align a variable to the nearest higher 'k'-byte address *
* boundary. 'k' must be substituted with a suitable constant *
* number when the ModBuf_X(k) or ModBuf_Y(k) macro is invoked. *
* In most cases, variables are aligned either to avoid potential *
* misaligned memory accesses, or to configure a modulo buffer. *
* *
* 4) The __interrupt__ attribute is used to qualify a function as an *
* interrupt service routine. An interrupt routine can be further *
* configured to save certain variables on the stack, using the *
* __save__(var-list) directive. *
* *
* 5) The __shadow__ attribute is used to set up any function to *
* perform a fast context save using shadow registers. *
* *
* 6) Note the use of double-underscores (__) at the start and end of *
* all the keywords mentioned above. *
