11. UART0/1
The UART is a general-purpose serial data communications interface for synchronous or asynchronous com-
munication with external devices.
The UART has a clock-synchronous/clock-asynchronous two-way communications feature .
Also supplies a master/slave communications feature (multi-processor mode) . (It can be used only master
side.)
Interrupts can be generated upon send complete, receive complete, or reception error detection.
Supports extended intelligent I/O service (EI2OS) .
UART0/1 Functions
Note : During clock-synchronous forwarding, just the data is forwarded, with no stop or start bit appended.
Functions
Data Buffer
Full-duplex double buffer
Transfer mode
Clock-synchronous (no start, stop, or parity bit)
Clock-asynchronous (start-stop synchronization)
Baud Rate
Select from 8 dedicated baud rate generators
External clock input possible
Clock supplied from internal timer (16-bit reload timer 0) available
Data length
7-bit (asynchronous normal mode only)
8-bit
Signal method
Non Return to Zero (NRZ)
Reception Error Detection
Framing error
Overrun error
Parity error (not available in operation mode 1 (multi processor mode) )
Interrupt Requests
Receive interrupt (reception complete, reception error detected)
Send interrupt (send complete)
Both send and receive support extended intelligent I/O service (EI2OS)
Master/Slave Communications
Function
(In multiprocessor mode)
1-to-n (master to slave) communication available (can only be used as master)
