Working Principle
The R8C core is a 16-bit CISC processor derived from the M16C architecture with simplified instruction set for code density. The CPU uses a register-plus-memory architecture with 16-bit registers (R0-R3) and address registers (A0-A1). On-chip flash supports self-programming for boot-loader applications. Timer modules support PWM output, input capture, and event counting. The data flash area simulates EEPROM for parameter storage.
Applications
