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.

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.

◆ lpc32xx_idle()

void* lpc32xx_idle ( 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 lpc32xx_idle
#include <confdefs.h>

Variable Documentation

◆ lpc32xx_magic_zero_begin

uint32_t lpc32xx_magic_zero_begin[]

Begin of magic zero area.

A read from this area returns zero. Writes have no effect.

◆ lpc32xx_magic_zero_end

uint32_t lpc32xx_magic_zero_end[]

End of magic zero area.

A read from this area returns zero. Writes have no effect.

◆ lpc32xx_magic_zero_size

uint32_t lpc32xx_magic_zero_size[]

Size of magic zero area.

A read from this area returns zero. Writes have no effect.
