The BRSR registers are not initialized by a reset.
6.2.22
BRDRH
BRDRL
The branch destination registers (BRDR) comprise a set of four 32-bit read-only registers. These
registers store the branch destination fetch addresses used when performing a PC trace. The
BRDR registers form a FIFO (first-in first-out) queue for PC trace use. The queue is shifted at
each branch.
The BRDR registers are not initialized by a reset.
