Data Structures

struct  leon3_timecounter
 Represents the LEON3-specific timecounter. More...
 

Macros

#define LEON3_REG_CACHE_CTRL_FI   0x00200000U
 This constant represents the flush instruction cache flag of the LEON cache control register.
 
#define LEON3_REG_CACHE_CTRL_DS   0x00800000U
 This constant represents the data cache snooping enable flag of the LEON cache control register.
 
#define LEON3_CLOCK_INDEX   0
 This constant defines the index of the GPTIMER timer used by the clock driver.
 
#define LEON3_COUNTER_GPTIMER_INDEX   ( LEON3_CLOCK_INDEX + 1 )
 This constant defines the index of the GPTIMER timer used by the CPU counter if the CPU counter uses the GPTIMER.
 
#define LEON3_GPTIMER_0_FREQUENCY_SET_BY_BOOT_LOADER   1000000
 This constant defines the frequency set by the boot loader of the first GPTIMER instance.
 

Functions

RTEMS_NO_RETURN void leon3_power_down_loop (void)
 Sets asr19 to zero to enter the power-down mode of the processor in an infinite loop.
 

Variables

int leon3_timer_core_index
