TX_LENGTH (offset = 0x18)
The total frame length (starting from destination address to the end of frame, excluding CRC field)
should be written to this register.

RX_BADDR (offset = 0x1C)
The starting address of RX buffer to store incoming frame is written to this register. RX_BADDR
can hold 15 entries of the start address of RX buffer. The number of entries not taken for RX
processing can be read from bits[10:8] of RX_BUFLVL (offset = 0x24). Not assigning a buffer
address in time will result in an interrupt (if enabled) with INT_SRC bit[5] and the frame will be
dropped.
