Description
Transmit Enable
When this bit is set to 1, transmission is enabled. Under
this condition, serial transmission is started by writing
transmit data to TDR, and clearing the TDRE flag in SSR
to 0. Note that SMR should be set prior to setting the TE
bit to 1 in order to designate the transmission format.
If transmission is halted by clearing this bit to 0, the
TDRE flag in SSR is fixed 1.
Receive Enable
When this bit is set to 1, reception is enabled. Under this
condition, serial reception is started by detecting the start
bit in asynchronous mode or the synchronous clock input
in clocked synchronous mode. Note that SMR should be
set prior to setting the RE bit to 1 in order to designate
the reception format.
Even if reception is halted by clearing this bit to 0, the
RDRF, FER, PER, and ORER flags are not affected and
the previous value is retained.
Multiprocessor Interrupt Enable (valid only when the MP
bit in SMR is 1 in asynchronous mode)
When this bit is set to 1, receive data in which the
multiprocessor bit is 0 is skipped, and setting of the
RDRF, FER, and ORER status flags in SSR is disabled.
On receiving data in which the multiprocessor bit is 1, this
bit is automatically cleared and normal reception is
resumed. For details, see section 14.5, Multiprocessor
Communication Function.
When receive data including MPB = 0 in SSR is being
received, transfer of the received data from RSR to RDR,
detection of reception errors, and the settings of RDRF,
FER, and ORER flags in SSR are not performed. When
receive data including MPB = 1 is received, the MPB bit
in SSR is set to 1, the MPIE bit is automatically cleared to
0, and RXI and ERI interrupt requests (in the case where
the TIE and RIE bits in SCR are set to 1) and setting of
the FER and ORER flags are enabled.
