OUTPUT DRIVE CURRENTS
Figure 43 through Figure 57 show typical current-voltage char-
acteristics for the output drivers of the ADSP-BF52x processors.
The curves represent the current drive capability of the output
drivers. See Table 10 on Page 23 for information about which
driver type corresponds to a particular ball.
