1) Keeping signal levels within the limits specified in this table, ensures operation without overload conditions.
For signal levels outside these specifications, also refer to the specification of the overload current I_OV.
2) This parameter is tested for P3, P9.
3) The maximum deliverable output current of a port driver depends on the selected output driver mode, see
Table 4-4, Current Limits for Port Output Drivers. The limit for pin groups must be respected.
4) As a rule, with decreasing output current the output levels approach the respective supply level (V_OL → V_SS,
V_OH → V_DDP). However, only the levels for nominal output currents are guaranteed.
5) This specification is not valid for outputs which are switched to open drain mode. In this case the respective
output will float and the voltage results from the external circuitry.
6) An additional error current (I_INJ) will flow if an overload current flows through an adjacent pin. Please refer to
the definition of the overload coupling factor K_OV.
7) The driver of P3.15 is designed for faster switching, because this pin can deliver the system clock (CLKOUT).
The maximum leakage current for P3.15 is, therefore, increased to 1µA.
8) During a hardware reset this specification is valid for configuration on P1H.4, P1H.5, P9.4 and P9.5.
After a hardware reset this specification is valid for NMI.
9) The maximum current may be drawn while the respective signal line remains inactive.
10) The minimum current must be drawn to drive the respective signal line active.
11) Not subject to production test - verified by design/characterization.

1) An output current above |I_OXnom| may be drawn from up to three pins at the same time.
For any group of 16 neighboring port output pins the total output current in each direction (ΣI_OL and Σ-I_OH) must
remain below 50 mA.
