Legend / Abbreviations for
Table 3
:
Type:
I = input, O = output, S = supply, HiZ= high impedance,
In/Output level: T
T
= TTL 0.8V / 2V with input trigger
C
T
= CMOS 0.3V
DD
/0.7V
DD
with input trigger
Port and control configuration:
– Input:
pu/pd = with internal 100k
weak pull-up or pull down
– Output:
OD = open drain
(logic level)
PP = push-pull
Interrupts:
INTx =external interrupt line
WUPx =Wake-Up interrupt line
The reset state of the I/O ports is input floating. To avoid excess power consumption, unused I/O ports
must be tied to ground.
