Description
Transmit Interrupt Enable
When this bit is set to 1, TXI interrupt request is
enabled. TXI interrupt request cancellation can be
performed by reading 1 from the TDRE flag, then
clearing it to 0, or clearing the TIE bit to 0.
Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt
requests are enabled.
RXI and ERI interrupt request cancellation can be
performed by reading 1 from the RDRF flag, or the
FER, PER, or ORER flag, then clearing the flag to
0, or by clearing the RIE bit to 0.
Transmit Enable
When this bit is set to 1, transmission is enabled.
In this state, serial transmission is started when
transmit data is written to TDR and the TDRE flag
in SSR is cleared to 0. SMR setting must be
performed to decide the transfer format before
setting the TE bit to 1.
The TDRE flag in SSR is fixed at 1 if transmission
is disabled by clearing this bit to 0.
Receive Enable
When this bit is set to 1, reception is enabled.
Serial reception is started in this state when a start
bit is detected in asynchronous mode or serial
clock input is detected in clocked synchronous
mode. SMR setting must be performed to decide
the transfer format before setting the RE bit to 1.
Clearing the RE bit to 0 does not affect the RDRF,
FER, PER, and ORER flags, which retain their
states.
Multiprocessor Interrupt Enable (enabled only
when the MP bit in SMR is 1 in asynchronous
mode)
Write 0 to this bit in Smart Card interface mode.
