Table 34 Subcode general (input/output pointers)
7.3.2.1
The subcode is buffered in the AUXSEGMENT register. Two offset pointers, SUBPOINTR-L and SUBPOINTR-H, and
SUBPOINTW-L and SUBPOINTW-H are associated with it. The R pointer is for the subcode output and the W pointer
for the subcode input.
Pointers are also provided to point at the offset into the AUXSEGMENT register where the start of a subcode frame will
be found, SUBBASEPOINTR-L and SUBBASEPOINTR-H and SUBBASEPOINTW-L and SUBBASEPOINTW-H. The
block copy engine is expected to use these to automatically move the subcode into the segment pointed at by
DRIVECURSEG register.
