UART/SIO Serial Mode Control Register 1 (SMC10)

UART/SIO serial mode control register 1(SMC10) controls the UART/SIO operation
mode. The register is used to set the serial data direction (endian), parity and its
polarity, stop bit length, operation mode (synchronous/asynchronous), data length, and
serial clock.
