The SCI-PHY/Any-PHY Output Configuration register (0x14) determines the cell
format on the output bus. Byte 0 or Word 0 will always contain the channel ID.
The cell length options for the 8 bit bus (shown in Fig. 6) are described in Table
14. 16 bit bus options (shown in Fig. 1) are described in Table 15.
