Hardware-division and single-cycle-multiplication
Integrated Nested Vectored Interrupt Controller (NVIC) providing deterministic interrupt
handling
42 interrupts with eight priority levels
Memory protection unit (MPU), providing a privileged mode for protected operating system
functionality
Unaligned data access, enabling data to be efficiently packed into memory
Atomic bit manipulation (bit-banding), delivering maximum memory utilization and streamlined
peripheral control
256 KB single-cycle flash

64 KB single-cycle SRAM
Four General-Purpose Timer Modules (GPTM), each of which provides two 16-bit
timer/counters. Each GPTM can be configured to operate independently as timers or event
counters (eight total): as a single 32-bit timer (four total), as one 32-bit Real-Time Clock (RTC)
to event capture, for Pulse Width Modulation (PWM), or to trigger analog-to-digital conversions
