Description
Parity Error
Indicates that a parity error has occurred during data field
reception. If a parity error occurs before data field
reception, the IEB immediately enters the wait state and
the PE flag is not set.
If a parity error occurs when the maximum number of
receive bytes in one frame has not been received, the PE
flag is not set. When a parity error occurs, the IEB returns
a NAK to the communications destination unit via the
acknowledge bit. In this case, the communications
destination unit continues retransfer up to the maximum
number of receive bytes in one frame and if the reception
has been completed normally by clearing the parity error,
the PE flag is not set. If the parity error is not cleared when
the reception is terminated before receiving data for the
number of bytes specified by the message length, the PE
flag is set.
In broadcast reception, if a parity error occurs during data
field reception, the IEB enters the wait state immediately
after setting the PE flag.
