[Solved]Write C Code Define Isr Handles Uart1 Peripheral Interrupt Teensy 32 B Enable Interrupt C Q37159610
just c and d.
a. Write the C code to define an ISR that handles UART1 peripheral interrupt on the Teensy 3.2. b. If you enable an interrupt in your C code, but don’t define the ISR, what code executes when the interrupt is triggered? c. According to the datasheet, Teensy 3.2 has 2 pin change interrupts, PCINTO and PCINT 1, yet al /O pins are “interruptable”. Explain how each pin change is serviced with only 2 pin change interrupts and how different events (rising, falling etc.) are captured Suppose we have a program with two ISRs, ISRO (priority O) and ISR1 (priority 1) defined below: int mainO d. while(1) void isroO disable.irq:/ disable interrupts do some stuff that takes 99 clock cycles enable-irq enable interrupts void isr10 disableirq): // disable interrupts /do some stuff that takes 142 clock cycles –enable-İrgl); //enable 1nterrupts If the datasheet states the interrupt latency is 15 cycles and nested interrupts are not supported, what is the system latency?
