This bit should be set by the user to achieve normal operation. If this bit is modified on the
fly, it will take effect at the beginning of the next frame (Ethernet, HDLC, and transparent)
or at the beginning of the next BD otherwise. MOT must be set if the data buffer is located
in external memory and has a 16-bit wide port size.
These bits contain the function code value used during this SDMA channel’s memory ac-
cesses. It is suggested that the user write bit FC3 with a one, to identify this SDMA chan-
nel access as a DMA-type access. Example: FC3–FC0 = 1000 (binary). Do not write the
value 0111 (binary) to these bits.

0 = Intel convention is used for byte ordering—swapped operation. It is also called lit-

1 = Motorola byte ordering—normal operation. It is also called big-endian byte order-
tle-endian byte ordering. The bytes stored in each buffer word are reversed as
compared to the Motorola mode.
ing. As data is received from the serial line and put into the buffer, the most signif-
icant byte of the buffer word contains data received earlier than the least significant
byte of the same buffer word.
tle-endian byte ordering. The transmission order of bytes within a buffer word is re-
versed as compared to the Motorola mode.
ing. As data is transmitted onto the serial line from the data buffer, the most signif-
icant byte of the buffer word contains data to be transmitted earlier than the least
significant byte of the same buffer word.
The MOT must be set if the data buffer is located in external
memory and has a 16-bit wide port size.
