Technical Context

The R5F56609BDFB#10 implements the RXv3 CPU core with 113 instructions, single-precision FPU, collective register bank save, and MPU-based memory protection. Its clock system integrates main (8–24 MHz crystal), sub (32.768 kHz), and on-chip oscillators (LOCO/HOCO/IWDT-dedicated), with independent PLL and frequency-division paths for ICLK (120 MHz), PCLKA (120 MHz), PCLKB (60 MHz), and ADCLK (60 MHz).

Peripheral integration includes CAN FD (ISO 11898-1:2015), 13 SCI channels (asynchronous/smart-card/SPI/I²C modes), 2 RIIC interfaces (400 kbps fast-mode), RSPI (30 Mbps), 24-channel S12ADH ADC (0.9 µs min conversion), 4-channel CMPC, and REMCa remote control receiver - all coordinated via the Event Link Controller (ELC) to minimize CPU intervention during low-power operation.
