Technical Context

The R5F56604BGFB#30 implements the RXv3 CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, and 16 register banks for fast context switching. Its clock system integrates PLL, HOCO (16/18/20 MHz), LOCO (240 kHz), and IWDT-dedicated oscillator, enabling independent domain clocks: ICLK up to 120 MHz, PCLKA up to 120 MHz (MTU3a, RSPI), PCLKB up to 60 MHz (TMR, CMT), and ADCLK up to 60 MHz for S12ADH.

Peripheral integration includes ELC for interrupt-free inter-module triggering (83 internal events), MTU3a with 9 channels supporting complementary PWM for 3-phase inverters (with dead-time auto-generation), and dual SCIm with 16-byte FIFOs. Safety architecture comprises MPU (8 regions), Trusted Memory (TM), CRC calculator (CRCA), DOCA, and CAC for clock accuracy monitoring - all aligned with IEC60730 Class B requirements.
