Notes: 1. The allowable input current is the maximum value of the current flowing from each I/O
pin to V
SS
(except for port 8, SCL and SDA).
2. The allowable input current is the maximum value of the current flowing from each I/O
pin to V
SS
. This applies to port 8.
3. The allowable input current is the maximum value of the current flowing from each I/O
pin to V
SS
. This applies to SCL and SDA.
4. The allowable output current is the maximum value of the current flowing from V
CC
to
each I/O pin.
5. The total allowable input current is the sum of the currents flowing from all I/O pins to
V
SS
simultaneously.
6. The total allowable output current is the sum of the currents flowing from V
CC
to all I/O
pins.
