We support + alignment slimbridges by noting that an overflow size word must have a slot count of at least 255. Any value + less than 128 indicates a slim bridge, which gives us 7 bits, organized as a 3-bit alignment field (in bits 4 to 6), + and a 4-bit bridge size field (in bIts 0 to 3). The bridge size field gives the size minus one in words of the + slimbridge. A size of zero specifies an 8-byte, one word slimbridge, a size of 15 implies an 128 byte, 16 word + slimbridge.
