ABRT_SLVRD_INTX
1: When the processor side responds to a slave mode
request for data to be transmitted to a remote master and
user writes a 1 in CMD (bit 8) of 2IC_DATA_CMD register

ABRT_SLV_ARBLOS 1: Slave lost the bus while transmitting data to a remote

T
master.
I2C_TX_ABRT_SOURCE[12] is set at the same time. Note:
Even though the slave never "owns" the bus, something
could go wrong on the bus. This is a fail safe check. For
instance, during a data transmission at the low-to-high tran-
sition of SCL, if what is on the data bus is not what is sup-
posed to be transmitted, then the controller no longer own
the bus.

ABRT_SLVFLUSH_T
XFIFO
1: Slave has received a read command and some data
exists in the TX FIFO so the slave issues a TX_ABRT inter-
rupt to flush old data in TX FIFO.

ARB_LOST
1: Master has lost arbitration, or if
I2C_TX_ABRT_SOURCE[14] is also set, then the slave
transmitter has lost arbitration. Note: I2C can be both master
and slave at the same time.
