1) An output current above |I
OXnom| may be drawn from up to three pins (P2.7-P2.0 only) at the same time.
For any group of 16 neighboring port output pins the total output current in each direction (
ΣIOL and/or Σ-IOH)
must remain below 50 mA.
2) Valid for V
OL in bidirectional reset mode only.

1) The supply current is a function of the operating frequency. This dependency is illustrated in Figure 10.
These parameters are tested at
VDDmax and maximum CPU clock with all outputs disconnected and all inputs
at

3) This parameter is determined mainly by the current consumed by the oscillator (see Figure 9). This current,
however, is influenced by the external oscillator circuitry (crystal, capacitors). The values given refer to a typical
circuitry and may change in case of a not optimized external oscillator circuitry (see also application notes
AP2420: Crystal Oscillator, AP2424: Ceramic Resonator Oscillator).
