7.4 SysTick
The count clock frequency varies with each product, and so the value set in the SysTick Calibration Value
Register also varies with each product.
SysTick Control and Status Register, the counter loads with the value set in the Reload Value Register
and begins counting down. When the counter reaches “0”, a SysTick exception occurs. You may be
pending exceptions and use a flag to know when the timer reaches “0”.
(Note)
SysTick provides interrupt features using the CPU’s system timer.
When you set a value in the SysTick Reload Value Register and enable the SysTick features in the
The SysTick Calibration Value Register holds a reload value for counting 10 ms with the system timer.
In this product, the system timer counts based on a clock obtained by dividing the
clock input from the X1 pin by 32.
The SysTick Calibration Value Register is set to 0x9C4, which provides 10 ms timing
when the clock input from X1 is 8 MHz. In case of 10MHz clock input, 10 ms timing is
made by setting 0xC35 to SysTick Reload Register.
