XPS_LL_TEMAC Ethernet core provides a control interface to internal registers via a 32-bit Processor Local Bus (PLB) Version 4.6 as described in the IBM CoreConnect™ 128-Bit Processor Local Bus, Architectural Specification Version 4.6. This PLB slave interface supports single beat read and write data transfers (no burst transfers).
