Port and control configuration:
– Input:
float = floating, wpu = weak pull-up, int = interrupt
1)
, ana = analog
– Output:
OD = open drain
2)
, PP = push-pull
Refer to
Section 12 "I/O PORTS" on page 39
for more details on the software configuration of the I/O
ports.
The RESET configuration of each pin is shown in bold. This configuration is valid as long as the device is
in reset state.
