Section 10 Ethernet Controller Direct Memory Access Controller (E-DMAC)
Bits 0—Reserved: This bit is always read as 0. The write value should always be 0.
10.2.14 Receiving-Buffer Write Address Register (RBWAR)
This is the register for storing the buffer address to be written in the receiving buffer when the E-
DMAC writes data in the receiving buffer. Which addresses in the receiving buffer are processed
by the E-DMAC can be recognized by monitoring addresses displayed in this register.

Note: The buffer write processing result from the E-DMAC and the value read by the register
may not be the same.
