11.2.12 Branch Destination Register (BRDR)
BRDR is a 32-bit read-only register. BRDR stores bits 27 to 0 in the address of the branch
destination instruction. BRDR has the flag bit that is set to 1 when a branch occurs. This flag bit is
cleared to 0 when BRDR is read, the setting to enable PC trace is made, or BRDR is initialized by
a power-on reset. Other bits are not initialized by a power-on reset. The eight BRDR registers
have a queue structure and a stored register is shifted at every branch.
