14. UART
UART is the general-purpose serial data communications interface to carry out synchronous or asynchronous
communication (start-stop synchronization) with external systems. It has a master/slave-type communications
function (multiprocessor mode: supporting only master side) as well as normal bi-directional communications
function (normal mode).
UART Functions
UART is the general-purpose serial data communications interface that sends and receives serial data to/from
other CPUs and peripheral equipment, and has functions shown in Table 16.1-1.
Table 16.1-1 UART Functions
Note : Start
/
stop bits are not added by UART and only data is transferred.

data selection bit (A/D) to be used to control communications.
*2 : 1-bit only can be detected for stop bit in case of reception.

Dedicated baud rate generator is available. Can be selected from 8 types.
External clock input is possible.
Internal clock (Internal clocks that are provided from 16-bit reload timer support-
ing each channel can be used.)

Non Return to Zero (NRZ) method
Reception error detection
Framing error
Overrun error
Parity error (impossible in case of multiprocessor mode)
Interruption request
Reception interruption (reception completion, reception error detection)

(Multiprocessor mode)
Communication between 1 (master) and n (slaves) is possible
(Only supports master side)
