PACKET RAM
The packet RAM consists of 256 bytes of memory space. The
first 16 bytes of this memory space are allocated for use by the
on-chip processor. The remaining 240 bytes of this memory
space are allocated for storage of data from valid received packets
and packet data to be transmitted. The communications processor
stores received payload data at the memory location indicated
by the value of the RX_BASE_ADR register (Address 0x125),
the receive address pointer. The value of the TX_BASE_ADR

register (Address 0x124), the transmit address pointer, determines
the start address of data to be transmitted by the communications
processor. This memory can be arbitrarily assigned to store
single or multiple transmit or receive packets, with and without
overlap. The RX_BASE_ADR value should be chosen to ensure
that there is enough allocated packet RAM space for the
maximum receiver payload length.
