For signal levels outside these specifications, also refer to the specification of the overload current IOV. 2) This parameter is tested for P3, P4, P9. 3) The maximum deliverable output current of a port driver depends on the selected output driver mode, see Table 12, 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 ( VOL → VSS, VOH → VDDP). 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 ( IINJ) will flow if an overload current flows through an adjacent pin. Please refer to the definition of the overload coupling factor KOV. 7) The driver of P3.15 is designed for faster switching, because this pin can deliver the reference clock for the bus interface (CLKOUT). The maximum leakage current for P3.15 is, therefore, increased to 1 µA. 8) This specification is valid during Reset for configuration on RD, WR, EA, PORT0 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) This specification is valid during Reset for configuration on ALE. 12) This specification is valid during Reset for pins P4.3-0, which can act as CS outputs, and for P3.12. 13) Not subject to production test - verified by design/characterization. Table 12 Current Limits for Port Output Drivers Port Output Driver Mode Maximum Output Current ( I OLmax, -IOHmax) 1) 1) An output current above | IOXnom| 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-IOH) must remain below 50 mA. Nominal Output Current ( I OLnom, -IOHnom) Strong driver 10 mA 2.5 mA Medium driver 4.0 mA 1.0 mA Weak driver 0.5 mA 0.1 mA Table 11 DC Characteristics (Operating Conditions apply)1) (cont’d) Parameter Symbol Limit Values Unit Test Condition Min.
