Bit 31—BRDR Valid Flag (DVF): Indicates whether a branch destination address is stored.
When a branch destination address is fetched, this flag is set to 1. This flag is set to 0 in reading
BRDR.
Bit 31: DVF
Description
0
The value of BRDR register is invalid
1
The value of BRDR register is valid
Bits 30 to 28—Reserved: These bits are always read as 0. The write value should always be 0.
Bits 27 to 0—Branch Destination Address (BDA27 to BDA0): These bits store the first fetched
address after branch.
