2a.Stall (NOP)
3. MOV.b W0,PORTB
Two-word instructions for DO. In these instruc-
tions, the fetch after the instruction contains an
address offset. This address offset is added to
the first instruction address to generate the last
loop instruction address. Therefore, these
instructions require 2 cycles, as shown in
Figure 2-7.
Instructions that are subjected to a stall due to a
data dependency between the X RAGU and X
WAGU. An additional cycle is inserted to resolve
the resource conflict, as shown in Figure 2-8.
Instruction stalls caused by data dependencies
are further discussed in Section 4.0.
