• Buffer write error (
[0] The current master receive has not detected a receive buffer
write error.
[1] The current master transfer was aborted due to a receive buffer
write error. The receive buffer and receive shift register were both
full at the same time. This bit is W1C.
• Buffer read error (
[0] The current master transmit has not detected a buffer read
error.
[1] The current master transfer was aborted due to a transmit buf-
fer read error. At the time data was required by the transmit shift
register the buffer was empty. This bit is W1C.
• Data not acknowledged (
[0] The current master receive has not detected a NAK during data
transmission.
[1] The current master transfer was aborted due to the detection of
a NAK during data transmission. This bit is W1C.
• Address not acknowledged (
[0] The current master transmit has not detected NAK during
addressing.
[1] The current master transfer was aborted due to the detection of
