signal designations
In both Figures 1 and 2, the polarity indicators (
with respect to the function shown inside the symbol and the symbols are the same in both figures. The signal
designations in Figure 1 agree with the indicated internal functions based on active-low data and are for use
with the logic functions and arithmetic operations shown in Table 1. The signal designations have been changed
in Figure 2 to accommodate the logic functions and arithmetic operations for the active-high data given in
Table 2.
