7.10.7.1 BD TABLE POINTER (RBASE, TBASE). The RBASE and TBASE entries define
the starting location in the dual-port RAM for the set of BDs for receive and transmit func-
tions of the SCC. This provides a great deal of flexibility in how BDs for an SCC are parti-
tioned. By selecting RBASE and TBASE entries for all SCCs, and by setting the W-bit in the
last BD in each BD list, the user may select how many BDs to allocate for the transmit and
receive side of every SCC. The user must initialize these entries before enabling the corre-
sponding channel. Furthermore, the user should not configure BD tables of two enabled
SCCs to overlap, or erratic operation will occur.
7.10.7.2 SCC FUNCTION CODE REGISTERS (RFCR, TFCR). There are eight separate
function code registers for the four SCC channels: four for receive data buffers (RFCRx) and
four for transmit data buffers (TFCRx). The FC entry contains the value that the user would
like to appear on the function code pins FC3–FC0 when the associated SDMA channel
accesses memory. It also controls the byte-ordering convention to be used in the transfers.
