R/W Device Select
When the host controller function is selected, these
bits specify the peripheral device address. When the
function controller function is selected, this bit should
be set to B'00.

R/W Maximum Packet Size
These bits specify the maximum packet size for the
corresponding pipe.
These bits should be set to a value defined by the
USB specification for each transfer type.
Note: The initial value of MXPS is H'000 when no pipe is selected with the PIPESEL bits in
PIPESEL and H'040 when a pipe is selected with the PIPESEL bit in PIPESEL.
