PROCESSOR—ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in Table 20 may cause perma-
nent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.
Table 22 specifies the maximum total source/sink (I
OH
/I
OL
) cur-
rent for a group of pins. Permanent damage can occur if this
value is exceeded. To understand this specification, if pins PG5,
PG6, PG7, PG8, and PG9 from group 5 in the Total Current Pin
Groups table, each were sourcing or sinking 2 mA each, the
total current for those pins would be 10 mA. This would allow
up to 66 mA total that could be sourced or sunk by the remain-
ing pins in the group without damaging the device. For a list of
all groups and their pins, see the Total Current Pin Groups
table. Note that the V
OL
and V
OL
specifications have separate
per-pin maximum current requirements, see the Processor—
Electrical Characteristics table.

The individual values cannot be combined for analysis of a single instance of
overshoot or undershoot. The worst case observed value must fall within one of
the voltages specified, and the total duration of the overshoot or undershoot
(exceeding the 100% case) must be less than or equal to the corresponding duty
cycle.

Duty cycle refers to the percentage of time the signal exceeds the value for the
100% case. The is equivalent to the measured duration of a single instance of
overshoot or undershoot as a percentage of the period of occurrence.
