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
IOV.
2)
If XTAL3 is driven by a crystal, reaching an amplitude (peak to peak) of 0.25
× V
DDI is sufficient.
3)
This parameter is tested for P2, P3, P4, P6, P7, P9.
4)
The maximum deliverable output current of a port driver depends on the selected output driver mode, see
5)
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.
6)
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.
7)
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.
8)
This specification is valid during Reset for configuration on RD, WR, EA, PORT0.
The pull-ups on RD and WR (WRL/WRH) are also active during bus hold.
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.
The pull-down on ALE is also active during bus hold.
12) This specification is valid during Reset for pins P6.4-0, which can act as CS outputs.
The pull-ups on CS outputs are also active during bus hold.
13) Not 100% tested, guaranteed by design and characterization.
