Type:
I = input, O = output, S = supply
In/Output level: C= CMOS 0.15V

Output level:
HS = 20mA high sink (on N-buffer only)
Port and control configuration:
– Input:
float = floating, wpu = weak pull-up, int = interrupt
1)
, ana = analog
– Output:
OD = open drain
2)
, PP = push-pull
Table 1. Device Pin Description
Note:
In the interrupt input column, “ei
x
” defines the associated external interrupt vector. If the weak pull-up col-
umn (wpu) is merged with the interrupt column (int), then the I/O configuration is pull-up interrupt input,
else the configuration is floating interrupt input.

Caution:
During reset, this pin
must be held at high level to avoid
entering ICC mode unexpectedly
(this is guaranteed by the internal
pull-up if the application leaves the
pin floating).
