Bits [15 0] Cell Extraction
EXTRST
The EXTRST is used to reset the Microprocessor Extract Cell Interface. When EXTRST is
set to logic 0, the Extract FIFO operates normally. When EXTRST is logic 1, the extract
FIFO is immediately emptied and ignores writes. The extract FIFO remains empty and
continues to ignore writes until a logic 0 is written to EXTRST. While asserted, EXTRST
overrides all other bits affecting the Microprocessor Extract Cell Interface.
DMAREQINV
The DMAREQINV bit inverts the polarity of the UP_DMAREQ output. If DMAREQINV is
a logic 0, the UP_DMAREQ output is active high. If DMAREQINV is a logic 1, the
UP_DMAREQ output is active low.
