v.
Reference numbers have been added for the operational
words shown in Table 2-1 to aid in the explanation of
the changes.
The action control bits (2,1,0) of Op Word
Examples 2, 3 and
4 should be 000 (no action for conditional action bits).
The 001 setting is not necessary because conditional
action bits are not involved, also 001 takes about 30us
longer to process by the CCM.
Two other changes are' noted for Op Word 6:
Bit 6 should be 0; there is no reason for it to be 1.
Bit 13 should be 1 because the EOM sequence should call
for command termination.
Note:
There may be minor variations in the other
examples of operational word construction
presented in the CCM manual.
Any discrepancies
will be resolved in favor of this latest
operational word description, and will be
included in a reissue of the CCM manual to
appear shortly.
