Set on each clock low timeout. The timeout value can be set in CLTO bitfield in the I2Cn_CTRL register.
BITO
Set on each bus idle timeout. The timeout value can be set in the BITO bitfield in the I2Cn_CTRL register.
RXUF
Set when data is read from the receive buffer through the I2Cn_RXDATA register while the receive buffer is empty.
TXOF
Set when data is written to the transmit buffer while the transmit buffer is full.
BUSHOLD
Set when the bus becomes held by the I
BUSERR
Set when a bus error is detected. The bus error is resolved automatically, but the current transfer is aborted.
ARBLOST
Set when arbitration is lost.
MSTOP
Set when a STOP condition has been successfully transmitted. If arbitration is lost during the transmission of the STOP condition,
then the MSTOP interrupt flag is not set.
NACK
Set when a NACK has been received.
ACK
Set when an ACK has been received.
RXDATAV
Set when data is available in the receive buffer. Cleared automatically when the receive buffer is read.
TXBL
Set when the transmit buffer becomes empty. Cleared automatically when new data is written to the transmit buffer.
TXC
Set when the transmit shift register becomes empty and there is no more data in the transmit buffer.
ADDR
Set when incoming address is accepted, i.e. own address or general call address is received.
RSTART
Set when a repeated start condition is detected.
START
Set when a start condition is successfully transmitted.
