Cortex m0+ systick
WebIn the Cortex-M0 and Cortex-M0+, the systick registers are located in the SCB and have different symbolic names to avoid confusion. The systick timer interrupt line and all of … WebThe systick timer The cortex m0 contains a 24 bit counter that can be used to generate periodic interrupts. Typically this is used as a timebase for an operating system (for example to allocate time slices) although this example will use it as a simple periodic interrupt source. The clock tree in the F0 discovery is a little tricky to get the ...
