Table
This status code indicates that no relevant information is available because the serial
interrupt flag, SI, is not yet set. This occurs between other states and when the I
is not involved in a serial transfer.
This status code indicates that a bus error has occurred during an I
bus error is caused when a START or STOP condition occurs at an illegal position in the
format frame. Examples of such illegal positions are during the serial transfer of an
address byte, a data byte, or an acknowledge bit. A bus error may also be caused when
external interference disturbs the internal I
set. To recover from a bus error, the STO flag must be set and SI must be cleared. This
