Bits 13 to 8: Receive Maximum Burst Length (RMBL[5:0]) – In POS-PHY Level 3, these six bits limit the
maximum number of four byte data groups that can be transferred from a port before switching to another port. The
maximum number of transfers is RMBL[5:0]+1 in 32-bit mode, 2*(RMBL[5:0]+1} in 16-bit mode, and
4*(RMBL[5:0]+1} in 8-bit mode. Note: if no other port is ready to start a transfer, transfer from the current port will
continue if the port contains more data than the almost empty level or contains an end of packet. These bits are
ignored in POS-PHY Level 2 or UTOPIA mode. A value of 00h disables the maximum burst length. In 32-bit mode,
a value of 01h is treated as 02h.
Bits 7 to 0: Receive System Loopback Bandwidth Limit (RLBL[7:0]) – These eight bits limit the maximum
bandwidth of a single port during system loopback. For RLBL[7:0] equals x, the bandwidth will be limited to 1/x of
the maximum system interface bandwidth. In 8-bit and 16-bit mode, a value of 00h is treated as 01h. In 32-bit
mode, a value of 01h or 00h is treated as 02h.
