OUTPUT DRIVE CURRENTS
Figure 36 through Figure 47 show typical current-voltage char-
acteristics for the output drivers of the processors. The curves
represent the current drive capability of the output drivers as a
function of output voltage. See Table 9 on Page 19 for informa-
tion about which driver type corresponds to a particular pin.
