pin is higher than VB/2 PB2 reads an high logic
level.
If the bit PWMI in DCSR register is set (see
Sec-
tion 3.2.1
), PWMI is directly connected with the In-
put Capture 2 on Timer 2, which is otherwise con-
nected in alternate function to PA7 (see
Figure
31
).
An internal pull down current generator (5uA) al-
lows to detect the Open Bus condition (external
pull up missing).
If the battery or ground connection are lost, the
PWMI line shows a controlled impedance charac-
teristic (see
Figure 30
)..
