7.5.1 Features
7.5 Nested Vectored Interrupt Controller (NVIC)
32 kB on-chip flash
The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M0. The
tight coupling to the CPU allows for low interrupt latency and efficient processing of late
arriving interrupts.
AHB peripherals
16 kB boot ROM
