Release Notes for StellarisWare Revision 5228 (October 1, 2009)

18.2.6 CANMessageSet() now provides ﬂag to enable FIFO mode. (Refer-

ence 10431)

The CANMessageSet() did not allow conﬁguring a set of message objects as a FIFO for transmitting

or receiving CAN messages. This change adds the MSG_OBJ_FIFO ﬂag value to tag message

objects as part of a FIFO and not the ﬁnal entry in a FIFO. This allows multiple message objects to

be linked together to transfer or receive more than 8 bytes at a time.

18.3 Bug Fixes in Stellaris Peripheral Driver Library

18.3.1 Remove uDMAIntStatus() and uDMAIntClear() APIs (Reference

10148)

The APIs that use the DMA_CHIS register have been deleted because this register is no longer

available for use and has been removed from the data sheet.

18.3.2 I2C_MASTER_CMD_BURST_RECEIVE_ERROR_STOP deﬁnition

corrected (Reference 10434)

The value of I2C_MASTER_CMD_BURST_RECEIVE_ERROR_STOP was incorrect; the correct

value is now provided.

18.3.3 CanBitRateSet() was incorrectly checking requested bit rate inputs.

(Reference 10439)

The function CanBitRateSet() function was incorrectly checking the limits for possible bit rates given

an input clock rate. The correct checking is now in place as ASSERT() checks to allow the param-

eter checking code to be removed in non-DEBUG builds.

18.3.4 Error in epi.h address size deﬁnitions corrected (Reference 10461)

An error in epi.h has been corrected and affected example applications have been updated.

Labels EPI_ADDR_PER_SIZE_512MB and EPI_ADDR_RAM_SIZE_512MB have been replaced

with the correct deﬁnitions for those register bit patterns, EPI_ADDR_PER_SIZE_256MB and

EPI_ADDR_RAM_SIZE_256MB.
