• If
•
R4=0b1111 1111 1111 1111 1111 1111 1111 1111
where this is the background bit field
•
R3=0b0000 1001 1010 1100 0000 1101 0000 1001
where bits 31–16 are the foreground bit field, bits 15–8 are
the position, and bits 7–0 are the length
then the Bit Field Deposit (unsigned) instruction produces:
•
R7=0b1111 1111 1111 0101 1001 1111 1111 1111
