Certain parameter RAM values above (marked in bold face) need to be initialized by the
user before the PIP is enabled; the others are initialized/written by the CP. Once initialized,
most parameter RAM values will not need to be accessed in user software since most of the
activity is centered around the transmit buffer descriptors, not the parameter RAM.
7.13.8.14 BUFFER DESCRIPTOR TABLE POINTER (RBASE). The RBASE entry defines
the starting location in the dual-port RAM for the PIP receiver’s set of buffer descriptors. This
provides a great deal of flexibility in how BDs are partitioned. By programming the RBASE
entry and by setting the "wrap" bit in the last BD, the user may select how many BDs to allo-
cate for the receive function. The user must initialize RBASE before enabling the channel.
7.13.8.15 CENTRONICS FUNCTION CODE REGISTER (CFCR). The FC entry contains
the value that the user would like to appear on the function code pins (FC3-0) when the
associated SDMA channel accesses memory. It also controls the byte ordering convention
to be used in the transfers.
