Parity Error
Indicates that a parity error occurred during
reception using parity addition in asynchronous
mode, causing abnormal termination.
[Setting condition]
When a parity error is detected during reception
If a parity error occurs, the receive data is
transferred to RDR but the RDRF flag is not set.
Also, subsequent serial reception cannot be
continued while the PER flag is set to 1. In clocked
synchronous mode, serial transmission cannot be
continued, either.
[Clearing condition]
When 0 is written to PER after reading PER = 1
The PER flag is not affected and retains its previous
state when the RE bit in SCR is cleared to 0.
2 TEND 1 R Transmit End
Indicates that transmission has been ended.
[Setting conditions]
• When the TE bit in SCR is 0
• When TDRE = 1 at transmission of the last bit
of a 1-byte serial transmit character
[Clearing conditions]
• When 0 is written to TDRE after reading TDRE
= 1
• When the DMAC

or the DTC

is activated by
a TXI interrupt request and transfer
transmission data to TDR
1 MPB 0 R Multiprocessor Bit
MPB stores the multiprocessor bit in the receive
data. When the RE bit in SCR is cleared to 0 its
previous state is retained.
0 MPBT 0 R/W Multiprocessor Bit Transfer
MPBT stores the multiprocessor bit to be added to
the transmit data.
