Bit Bit Name
Initial
Value
R/W Description
5 ORER 0 R/(W)* Overrun Error
[Setting condition]
When the next serial reception is completed while RDRF =
1
[Clearing condition]
When 0 is written to ORER after reading ORER = 1
4 FER 0 R/(W)* Framing Error
[Setting condition]
When the stop bit is 0
[Clearing condition]
When 0 is written to FER after reading FER = 1
In 2-stop-bit mode, only the first stop bit is checked.
3 PER 0 R/(W)* Parity Error
[Setting condition]
When a parity error is detected during reception
[Clearing condition]
When 0 is written to PER after reading PER = 1
2 TEND 1 R Transmit End
[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 a TXI interrupt request is issued allowing DTC
to write data to TDR
1 MPB 0 R Multiprocessor Bit
MPB stores the multiprocessor bit in the receive frame.
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 frame.
Note: * Only 0 can be written to clear the flag.
