MT90528 hardware revision.
In SDT mode, these bits hold the base word address of the port p SDT Segmentation
Pointer Table (see Figure 23 on page 63). In UDT mode, these bits form a pointer to the
base word address of the UDT Segmentation Control Structure associated with port p.
The SDT Segmentation Pointer Tables must start on 32-word (64-byte) boundaries.
Port p Configuration:
“00” = Port p is disabled
“01” = UDT mode
“10” = Reserved
“11” = SDT mode.
