ACKSTAT: Acknowledge Status bit
1 = NACK was detected last
0 = ACK was detected last
Hardware is set or clear at the end of Acknowledge.
TRSTAT: Transmit Status bit
(When operating as I
1 = Master transmit is in progress (8 bits + ACK)
0 = Master transmit is not in progress
Hardware is set at the beginning of master transmission; hardware is clear at the end of slave Acknowledge.
Unimplemented: Read as ‘0’
BCL: Master Bus Collision Detect bit
1 = A bus collision has been detected during a master operation
0 = No collision
Hardware is set at the detection of a bus collision.
GCSTAT: General Call Status bit
1 = General call address was received
0 = General call address was not received
Hardware is set when the address matches the general call address; hardware is clear at Stop detection.
ADD10: 10-Bit Address Status bit
1 = 10-bit address was matched
0 = 10-bit address was not matched
Hardware is set at the match of the 2
IWCOL: Write Collision Detect bit
1 = An attempt to write to the I2CxTRN register failed because the I
0 = No collision
Hardware is set at an occurrence of write to I2CxTRN while busy (cleared by software).
I2COV: Receive Overflow Flag bit
1 = A byte was received while the I2CxRCV register is still holding the previous byte
0 = No overflow
Hardware is set at an attempt to transfer I2CxRSR to I2CxRCV (cleared by software).
D/A: Data/Address bit (when operating as I
1 = Indicates that the last byte received was data
0 = Indicates that the last byte received was a device address
Hardware is clear at the device address match. Hardware is set after a transmission finishes or by
reception of a slave byte.
