UART
UART is a general purpose serial communication interface for synchronous or asynchronous (start-stop syn-
chronization) communications with external devices. It supports bi-directional communication (normal mode)
and master/slave communication (multi-processor mode: supported on master side only). An interrupt can be
generated upon completion of reception, detection of a reception error, or completion of transmission. EI
2
OS is
supported.
UART functions
UART, or a generic serial data communication interface that sends and receives serial data to and from other
CPU and peripherals, has the functions listed in following.
Note : In clock synchronous transfer mode, the UART transfers only data with no start or stop bit added.
UART operation modes
: Setting disabled
*1 :
+
1 is an address/data setting bit (A/D) which is used for communication control.
*2 : Only one bit can be detected as a stop bit at reception.
