In The Nested Vectored Interrupt Controller (NVIC) offers very fast interrupt handling and provides the vector table as a set of real vectors (addresses). Is the following statement correct?

the NVIC automatically saves and restores a set of the CPU registers (R0-R3, R12, PC, PSR, and LR), does a quick entry to the next pending interrupt without a complete pop/push sequence, and serves a complete set of 255 (240 external) interrupts.

List the interrupt handler names defined for the following interrupts in NVIC.

System timer

ADC interrupt

USART1 interrupt
