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

BRSR Valid Flag
Indicates whether the branch source address is stored.
When a branch source address is fetched, this flag is
set to 1. This flag is cleared to 0 by reading from
BRSR.
0: The value of BRSR register is invalid
1: The value of BRSR register is valid
Reserved
These bits are always read as 0. The write value
should always be 0.
Branch Source Address
Store bits 27 to 0 of the branch source address.
