PSoC4 SysTick interrupt | Cypress Semiconductor
PSoC4 SysTick interrupt
SysTick feature is supported in Cortex M0 and hence can be used in PSoC4 as system tick interrupt to control task switching.
SysTick is Cortex Vector #15. System API functions CyIntSetSysVector() and SysTick_Config() have to be used to initialize the SysTick and control its frequency
