The auto-baud feature may not calculate the correct
baud rate when the High Baud Rate Enable bit,
BRGH, is set. With the BRGH bit set, the baud rate
calculation used is the same as BRG = 0.
Work around
If the auto-baud feature is needed, use the Low
Baud Rate mode by clearing the BRGH bit.
Affected Silicon Revisions
With the auto-baud feature selected, the Sync
Break character (0x55) may be loaded into the
FIFO as data.
Work around
To prevent the Sync Break character from being
loaded into the FIFO, load the UxBRG register with
either 0x0000 or 0xFFFF prior to enabling the
auto-baud feature (ABAUD = 1).
Affected Silicon Revisions
Writing to I2CxTRN during a Start bit transmission
generates a write collision, indicated by the
IWCOL bit (I2CxSTAT<7>) being set. In this state,
additional writes to the I2CxTRN register should
be blocked. However, in this condition, the
I2CxTRN register can be written, although
transmissions will not occur until the IWCOL bit is
cleared in software.
Work around
After each write to the I2CxTRN register, read the
IWCOL bit to ensure a collision has not occurred.
If the IWCOL bit is set, it must be cleared in
software, and I2CxTRN register must be rewritten.

The ACKSTAT bit (I2CxSTAT<15>) only reflects
the received ACK/NACK status for master
transmissions, but not for Slave transmissions. As
a result, a slave cannot use this bit to determine
whether it received an ACK or a NACK from a
master. In future silicon revisions, the ACKSTAT
bit will reflect received ACK/NACK status for both
master and slave transmissions.
Work around
The SDA pin should be connected to any other
available I/O pin on the device. After transmitting a
byte, the slave should poll the SDA line (subject to
a time-out period that is dependent on the
application) to determine whether an ACK (‘0’) or
a NACK (‘1’) was received.
Affected Silicon Revisions
The D_A Status bit (I2CxSTAT<5>) is set on a
slave data reception in the I2CxRCV register, but
is not set on a slave write to the I2CxTRN register.
In future silicon revisions, the D_A bit will be set on
a slave write to the I2CxTRN register.
Work around
Use the D_A Status bit only for determining slave
reception status. Do not use it for determining
slave transmission status.
