Revision (See Manual for Details)
Figure replaced
To send a break signal during serial transmission, clear the
SPB0DT bit to 0 (designating low level), then clear the TE bit to
0 (halting transmission). When the TE bit is cleared to 0, the
transmitter is initialized regardless of its current state, and the
TxD pin becomes an output port outputting the value 0.
Handling of TEND Flag and TE Bit: The TEND flag is set to 1
when the stop bit of the final data segment is transmitted. If the
TE bit is cleared immediately after confirming that the TEND
flag was set, transmission may not complete properly because
stop bit transmission processing is still underway. Therefore,
wait at least 0.5 serial clock cycles (1.5 cycles if two stop bits
are used) after confirming that the TEND flag was set before
clearing the TE bit.
Description amended
The serial communication interface (SCI) supports a subset of
the ISO/IEC 7816-3 (identification cards) standard as an
extended function.
