If II
OH
exceeds the test condition, V
OH
may exceed the related specification. Pins are not
guaranteed to source current greater than the listed test condition.
4. Although each I/O port can sink more than the test conditions (20mA at V
CC
= 5V, 10mA at V
CC
=
3V) under steady state conditions (non-transient), the following must be observed:
4.1. The sum of all I
OL
, for ports C0 - C5, ADC7, ADC6 should not exceed 100mA.
4.2. The sum of all I
OL
, for ports B0 - B5, D5 - D7, XTAL1, XTAL2 should not exceed 100mA.
4.3. The sum of all I
OL
, for ports D0 - D4, RESET should not exceed 100mA.
If I
OL
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed
to sink current greater than the listed test condition.
