2.2.3 SH7670 Multiplex Pin Used on the SH7670 CPU Board
Table 2.2.9 to Table 2.2.15 list the function selections of SH7670 multiplex pin used on the SH7670 CPU board.
These pins are set to the port input pin as initial values. Thus, the MD bit of port control register should be set to
use the peripheral functions (except I/O port).
