BFF = 0, and channel n is enabled to
receive data.
Error flag is cleared.
BFF = 0, and channel n is enabled to
receive data.
Error flag is cleared.
SEmn = 0, and channel n stops
operation.
SEmn = 1, and channel n is enabled to
operate.

C (IIC10, IIC11, IIC20, IIC21) communication
This is to prevent an overrun error if
the next reception is completed
during error processing.
Error type is identified and the read
value is used to clear error flag.
Only error generated at the point of
reading can be cleared, by writing
the value read from the SSRmn
register to the SIRmn register
without modification.

Slave is not ready for reception
because ACK is not returned.
Therefore, a stop condition is
created, the bus is released, and
communication is started again from
the start condition. Or, a restart
condition is generated and
transmission can be redone from
address transmission.
