15.6.1 System Timer Control and status register
15.6.2 System Timer Reload value register
15.6.3 System Timer Current value register
15.6.4 System Timer Calibration value register (SYST_CALIB - 0xE000 E01C)
The SYST_CSR register contains control information for the SysTick timer and provides a
status flag. This register is part of the ARM Cortex-M0 core system timer register block.
For a bit description of this register, see
The SYST_RVR register is set to the value that will be loaded into the SysTick timer
whenever it counts down to zero. This register is loaded by software as part of timer
initialization. The SYST_CALIB register may be read and used as the value for
SYST_RVR register if the CPU is running at the frequency intended for use with the
SYST_CALIB value.
Table 175. System Timer Reload value register (SYST_RVR - 0xE000 E014) bit description
The SYST_CVR register returns the current count from the System Tick counter when it is
read by software.
