(1) The maximum total current, I
(OHmax), for all outputs combined should not exceed ±20 mA to hold the maximum voltage drop specified. See
Section 5.3 for more details.
(2) The maximum total current, I(OLmax), for all outputs combined should not exceed ±48 mA to hold the maximum voltage drop specified.
(3) The maximum total current, I(OLmax), for all outputs combined should not exceed ±100 mA to hold the maximum voltage drop specified.
Table 5-10 lists the output characteristics of the GPIOs in reduced drive strength mode.
