1. a) Write a function in C that uses Sys Tick delay for 1 millisecond. Assume that the Sys Tick is already initialized with NVIC-ST-RELOAD-Ox00FFFFFF, NVIC-ST-CTRL=0x05: Assume that the clock is running at 50 MHz, such that each bus cycle is 20 ns. b) Write a C function code that initializes the SysTick to interrupt every 100 us. In this initialization, in addition to enabling and arming SysTick interrupts you should also enable interrupts in the processor. Sys Tick ISR should run at priority level 1. Assume the bus clock is 80 MHz. You do not 1. a) Write a function in C that uses Sys Tick delay for 1 millisecond.
