 One serial data transfer format
 Receive error detection : Overrun errors detected
 The transmitter and receiver are mutually independent, enabling transmission and reception
 Double-buffering is used in both the transmitter and the receiver, enabling continuous

 Four interrupt sources — transmit-data-empty, transmit-end, receive-data-full, and receive
 The transmit-data-empty interrupt and receive data full interrupts can activate the data
 As the initial setting, SCI operation is halted. Register access is enabled by exiting module
