Transaction Done Interrupt. This flag is set if a transaction
completes successfully. It is cleared by writing a one to bit 0 of
the status register. It is unaffected by slave transactions.
Transaction has not completed.
Transaction completed.
Arbitration Failure Interrupt. When transmitting, if the SDA is low
when SDAOUT is high, then this I
another device on the bus. The Arbitration Failure bit is set when
this happens. It is cleared by writing a one to bit 1 of the status
register.
No arbitration failure on last transmission.
Arbitration failure occurred on last transmission.
No Acknowledge Interrupt. After every byte of data is sent, the
transmitter expects an acknowledge from the receiver. This bit is
set if the acknowledge is not received. It is cleared when a byte
is written to the master TX FIFO.
Last transmission received an acknowledge.
Last transmission did not receive an acknowledge.
Master Data Request Interrupt. Once a transmission is started,
the transmitter must have data to transmit as long as it isn’t
followed by a stop condition or it will hold SCL low until more
data is available. The Master Data Request bit is set when the
master transmitter is data-starved. If the master TX FIFO is
empty and the last byte did not have a STOP condition flag, then
SCL is held low until the CPU writes another byte to transmit.
This bit is cleared when a byte is written to the master TX FIFO.
Master transmitter does not need data.
Master transmitter needs data.
Slave Data Request Interrupt. Once a transmission is started,
the transmitter must have data to transmit as long as it isn’t
followed by a STOP condition or it will hold SCL low until more
data is available. The Slave Data Request bit is set when the
slave transmitter is data-starved. If the slave TX FIFO is empty
and the last byte transmitted was acknowledged, then SCL is
held low until the CPU writes another byte to transmit. This bit is
cleared when a byte is written to the slave Tx FIFO.
Slave transmitter does not need data.
Slave transmitter needs data.
Indicates whether the bus is busy. This bit is set when a START
condition has been seen. It is cleared when a STOP condition is
seen..
The current value of the SCL signal.
The current value of the SDA signal.
