The MIPS16e mode compresses 32-bit instructions into 16-bit encoding for up to 40% code size reduction. The 32 shadow register sets enable single-cycle interrupt context switching without register saving. The multi-port bus matrix connects the core to Flash (with 256-byte prefetch cache), SRAM, and peripherals. The Ethernet MAC interfaces with an external PHY via MII or RMII, with dedicated DMA channels for zero-CPU-overhead packet transfer. The USB OTG controller supports device, host, and OTG modes with on-chip PHY. Each CAN controller has dedicated DMA with 512 buffers. The 8-channel general DMA controller supports memory-to-memory and peripheral-to-memory transfers with configurable priorities. The RTCC module provides battery-backed timekeeping with alarm functions.","pin_description":"\n
