(1) Typical supply current values are based on device programmed but not configured, and no peripherals connected to any pins.
(2) The maximum total current, IOLmax, for all outputs combined, should not exceed 12 mA to hold the maximum voltage drop specified.
(3) The maximum total current, IOHmax, for all outputs combined, should not exceed 48 mA to hold the maximum voltage drop specified.
