;* File Name : 75x_init.s
;* Author : MCD Application Team
;* Date First Issued : 03/10/2006
;* Description : This module performs:
;* - Memory remapping (if required),
;* - Stack pointer initialisation for each mode ,
;* - Interrupt Controller Initialisation
;* - Branches to ?main in the C library (which eventually
;* calls main()).
;* On reset, the ARM core starts up in Supervisor (SVC) mode,
;* in ARM state,with IRQ and FIQ disabled.

// All numbers in the segment placement command lines below are interpreted

//
// When specifying the segment placement using the -P instead of the -Z
// option, the linker is free to split each segment into its segment parts
// and randomly place these parts within the given ranges in order to
// achieve a more efficient memory usage. One disadvantage, however, is
// that it is not possible to find the start or end address (using
// the assembler operators .sfb./.sfe.) of a segment which has been split
// and reformed.
//
// When generating an output file which is to be used for programming
// external ROM/Flash devices, the -M linker option is very useful
// (see xlink.pdf for details).

*
* 1 - The check task
* The 'check' task is responsible for ensuring that all the standard demo
* tasks are executing as expected. It only executes every three seconds, but
* has the highest priority within the system so is guaranteed to get execution
* time. Any errors discovered by the check task are latched until the
* processor is reset. At the end of each cycle the check task sends either
* a pass or fail message to the 'print' task for display on the LCD.
*
* 2 - The print task
* The print task is the LCD 'gatekeeper'. That is, it is the only task that
* should access the LCD directly so is always guaranteed exclusive (and
* therefore consistent) access. The print task simply blocks on a queue
* to wait for messages from other tasks wishing to display text on the LCD.
* When a message arrives it displays its contents on the LCD then blocks to
* wait again.
