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.
2)
The current ROM-version of the C164CI (step Ax) is equipped with port drivers, which provide reduced driving
capability and reduced control. Please refer to the actual errata sheet for details.

This parameter is determined mainly by the current consumed by the oscillator (see Figure 8). 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.
