Interface Bus Width Specification
Specifies an address to select the bus width when the
BSZ[1:0] of CS5BBCR are specified as 11. This bit is
valid only when area 5B is specified as MPX-I/O.
0: Selects the bus width by address A14
1: Selects the bus width by address A21
The relationship between the SZSEL bit and bus width
selected by A14 or A21 are summarized below.
