Description
Framing Error
[Setting condition]
•
[Clearing conditions]
•
•
In 2-stop-bit mode, only the first stop bit is checked.
The FER flag is not affected and retains their previous
values when the RE bit in SCR is cleared to 0.
Parity Error
[Setting condition]
•
[Clearing conditions]
•
•
The PER flag is not affected and retains their previous
values when the RE bit in SCR is cleared to 0.
Transmit End

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.
Multiprocessor Bit Transfer
MPBT sets the multiprocessor bit value to be added to
the transmit data.
When the stop bit is 0
Power-on reset or software standby mode
When 0 is written to FER after reading FER = 1
When a parity error is detected during reception
Power-on reset or software standby mode
When 0 is written to PER after reading PER = 1
Power-on reset or software standby mode
When the TE bit in SCR is 0
When TDRE = 1 at transmission of the last bit of a 1-
byte serial transmit character
When 0 is written to TDRE after reading TDRE = 1
