16 bits, the SH7616 connects D15–D8 to the least significant byte of the other bus master and D7–
D0 to the most significant byte.
Only data conversion is supported by this function. For this reason, be careful not to place
program code or constants in the CS2, CS4 space. When this function is used, make sure that the
access unit is the same for writing and reading. For example, data written by longword access
should be read by longword access. If the read access unit is different from the write access unit,
an incorrect value will be read.
