16.2
Table 16.1 shows the input/output pins for each SCI channel.
Table 16.1 Pin Configuration
Note:
16.3
The SCI has the following registers for each channel. Some bits in the serial mode register (SMR),
serial status register (SSR), and serial control register (SCR) have different functions in different
modes—normal serial communication interface mode and smart card interface mode; therefore,
the bits are described separately for each mode in the corresponding register sections.
