The R8C\/2G is an enhanced R8C family member with expanded peripheral set. The R8C core executes a 16-bit CISC instruction set with high code density. Additional timer channels support multiple PWM outputs for motor control and power conversion. The data flash region (4KB) simulates EEPROM for parameter storage without external memory. On-chip debugging (E1\/E20) supports real-time trace and breakpoint.<\/p>\n
