The modern architecture includes an event system for inter-peripheral communication without CPU overhead, and CCL (Configurable Custom Logic) blocks with programmable LUTs replacing external glue logic. UPDI interface simplifies programming and debugging.","working_principle":"The ATTINY414 executes AVR RISC instructions with most completing in one clock cycle. The event system allows peripherals to trigger actions in others without CPU intervention. CCL blocks provide programmable combinational logic. The 10-bit ADC can be triggered by events for automated sensor sampling. UPDI provides a single-pin interface for programming and debugging.","pin_description":"
