3.4.16 GPIO Interface Signals
Signal Name Ball No. Type Description Mux
GPIO0 D11 I/O GPIO Port 0. Each signal is configured independently as
an input or I/O, with or without static pull-up, and with
either open-drain or totem-pole output type.
A debouncer and an interrupt can be enabled or masked
for each of signals GPIO[00:01] and [06:15] indepen-
dently.
Note: GPIO12, GPIO13, GPIO16 inputs: If GPIOx func-
tion is selected but not used, tie GPIOx low.
