One-word, two-cycle instructions that are not
flow control instructions: the only instructions of
this type are the MOV.D (load and store double
word) instructions, as shown in Figure 2-4.
Table read/write instructions. These instructions
will suspend the fetching to insert a read or write
cycle to the program memory. The instruction
fetched, while executing the table operation, is
saved for 1 cycle and executed in the cycle
immediately after the table operation, as shown
in Figure 2-5.
Two-word instructions for CALL and GOTO. In
these instructions, the fetch after the instruction
provides the remainder of the jump or call desti-
nation address. These instructions require 2
cycles to execute, 1 cycle to fetch the 2 instruc-
tion words (enabled by a high speed path on the
second fetch), and 1 cycle to flush the pipeline,
as shown in Figure 2-6.
