- Clock Generation: A primary crystal oscillator (typically 24MHz or 32kHz for RTC) provides the clock source. The CPU contains internal PLLs to generate frequencies for the core and peripherals.
- Reset Circuit: A supervisor IC monitors the 3.3V rail. If voltage drops below a threshold, it holds the CPU in reset to prevent firmware corruption.
- JTAG/Debug Interface: The schematic includes an unpopulated header footprint for factory debugging and firmware flashing.
