When using the fetch immediate effective address (flea) or the calculate
The total head of some effective address types extends through the effective
where:
An example using the flea table and the X + op head notation is:
since there were no effective address (ea) additions. Therefore, Equation

address calculation and includes the head of the operation. These effective
address calculations are marked in the head column as follows:
Notice that the last instruction did not require the general Equation (11-2)
(11-1) is used:
in the timing calculations. For each effective address, a line is listed for word
The following calculations use the general Equation (11-2):
X is the head of the effective address alone.
