Detailed Description

Macro Definition Documentation

BSP_Convert_decrementer

#define BSP_Convert_decrementer

(

_value

)

Value:

(((unsigned long long) (_value)) / ((unsigned long long)bsp_clicks_per_usec))

Convert Decrementer ticks to microseconds.

Function Documentation

bsp_idle_thread()

void * bsp_idle_thread

(

uintptr_t

arg

)

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>
