11. UART Outline
UART is a general-purpose serial data communication interface for synchronous and asynchronous communi-
cation using external devices.
Provided with bi-directional communication function for both clock-synchronous and clock-asynchronous
modes.
Provided with master/slave communication function (multi-processor mode). (Only master side is available.)
Interrupt request is generated upon completion of reception, completion of transmission and detection of
reception error.
Ready for expanded intelligent service, EI
2
OS.
UART functions
Note : Start/stop bit is not added upon clock-synchronous transmission. Data only is transmitted.
UART operation modes
: Disallowed
*1 : “+1” is an address/data selection bit used for communication control (bit 11 of SCR1 register: A/D)
*2 : Only 1 bit is detected as a stop bit on data reception.
Description
Data buffer
Full-duplex double buffer
Transmission mode
Clock synchronous (No start/stop bit, no parity bit)
Clock asynchronous (start-stop synchronous)
Baud rate
Built-in special-purpose baud-rate generator. Setting is selectable
among 8 values.
Input of external values is allowed.
Use of clock from external timer (16-bit reload timer 0) is allowed.
Data length
7 bits (only asynchronous normal mode)
8 bits
Signaling system
Non Return to Zero (NRZ) system
Reception error detection
Framing error
Overrun error
Parity error (not detectable in operation mode 1 (multi-processor
mode))
Interrupt request
Receive interrupt (reception completed, reception error detected)
Transmission interrupt (transmission completed)
Ready for expanded intelligent I/O service (EI
2
OS) in both transmis-
sion and reception
Master/slave communication function
(asynchronous, multi-processor mode)
Communication between 1 (master) and n (slaves) are available
(usable as master only).
