Register Descriptions

The SCI has the following registers. 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. The bits, therefore,
are described separately for each mode in the corresponding register sections.
