Description
Transmit Enable
When this bit s 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. 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.
Reserved
The initial value should not be changed.
Transmit End Interrupt Enable
When this bit is set to 1, TEI interrupt request is
enabled. TEI cancellation can be performed by reading
1 from the TDRE flag in SSR, then clearing it to 0 and
clearing the TEND flag to 0, or by clearing the TEIE bit
to 0.
Clock Enable 1 and 0
Selects the clock source.
