7.2.11
BRSR is a 32-bit read register. BRSR stores the last fetched address before branch and the pointer
(3 bits) which indicates the number of cycles from fetch to execution for the last executed
instruction. BRSR has the flag bit that is set to 1 when branch occurs. This flag bit is cleared to 0,
when BRSR is read and also initialized by power-on resets or manual resets. Other bits are not
initialized by reset. Eight BRSR registers have queue structure and a stored register is shifted
every branch.
Note: * Undefined value
Bit 31—BRSR Valid Flag (SVF): Indicates whether the address and the pointer by which the
branch source address can be calculated. When a branch source address is fetched, this flag is set
to 1. This flag is cleared to 0 in reading BRSR.
