IC_TX_ABRT_SOURCE

         Name: I2C Transmit Abort Source Register
Size: 32 bits
Address Offset: 0x80
Read/Write Access: Read
This register has 32 bits that indicate the source
of the TX_ABRT bit. Except for Bit 9, this register is
cleared whenever the IC_CLR_TX_ABRT register or the
IC_CLR_INTR register is read. To clear Bit 9, the source
of the ABRT_SBYTE_NORSTRT must be fixed first; RESTART must
be enabled (IC_CON[5]=1), the SPECIAL bit must be cleared
(IC_TAR[11]), or the GC_OR_START bit must be cleared (IC_TAR[10]).
Once the source of the ABRT_SBYTE_NORSTRT is fixed, then this
bit can be cleared in the same manner as other bits in this
register. If the source of the ABRT_SBYTE_NORSTRT is not fixed
before attempting to clear this bit, Bit 9 clears for one cycle
and is then re-asserted.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

ABRT_SLV_ARBLOST

1: Slave lost the bus while transmitting

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
transition of SCL, if what is on the data
bus is not what is supposed to be
transmitted, then DW_apb_i2c no
longer own the bus.
