Description
[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.
[Setting condition]
When a parity error is detected during reception
[Clearing condition]
When 0 is written to PER after reading PER = 1
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 condition]
When 0 is written to TDRE after reading TDRE = 1
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.
Multiprocessor Bit Transfer
MPBT stores the multiprocessor bit to be added to
the transmit frame.
