Detailed Description

NXP LPC176X Board Support Package.

Function Documentation

bsp_idle_thread()

void * bsp_idle_thread

(

uintptr_t

ignored

)

Optimized idle task.

This idle task sets the power mode to idle. This causes the processor clock to be stopped, while on-chip peripherals remain active. Any enabled interrupt from a peripheral or an external interrupt source will cause the processor to resume execution.

To enable the idle task use the following in the system configuration:

#include <bsp.h>
 
#define CONFIGURE_INIT
 
#define CONFIGURE_IDLE_TASK_BODY bsp_idle_thread
 
#include <confdefs.h>

Optimized idle task.

The MSR[POW] bit is set to put the CPU into the low power mode defined in HID0. HID0 is set during starup in start.S.

bsp_restart()

void bsp_restart

(

const void *

addr

)

Restarts the bsp with "addr" address.

Parameters

addr	Address used to restart the bsp
