Description
Reserved. These bits are reserved.
I
This bit is set to 1 when a start condition is detected on the I
This bit is cleared when a stop condition is detected on the bus.
Master receive FIFO overflow.
This bit is set to 1 when a byte is written to the receive FIFO when it is already full.
This bit is cleared in all other conditions.
I
This bit is set to 1 when a transmission is complete between the master and the slave with which it was
communicating. If the I2CMCENI bit in I2CMCON is set, an interrupt is generated when this bit is set.
Clear this interrupt source.
I
This bit is set to 1 when a no acknowledge condition is received by the master in response to a data write transfer. If
the I2CNACKENI bit in I2CMCON is set, an interrupt is generated when this bit is set.
This bit is cleared in all other conditions.
I
Set to 1 when the master is busy processing a transaction.
Cleared if the master is ready or if another master device has control of the bus.
I
This bit is set to 1 when the I
interrupt is generated when this bit is set.
This bit is cleared in all other conditions.
I
This bit is set to 1 when a no acknowledge condition is received by the master in response to an address. If the
I2CNACKENI bit in I2CMCON is set, an interrupt is generated when this bit is set.
This bit is cleared in all other conditions.
I
This bit is set to 1 when data enters the receive FIFO. If the I2CMRENI in I2CMCON is set, an interrupt is generated.
This bit is cleared in all other conditions.
I
This bit goes high if the transmit FIFO is empty or contains only one byte and the master has transmitted an address
+ write. If the I2CMTENI bit in I2CMCON is set, an interrupt is generated when this bit is set.
This bit is cleared in all other conditions.

[00] = I
[01] = 1 byte in master transmit FIFO.
