NO CONNECTION PINS
Port 2 General-Purpose, Digital I/O Pins. These port pins function as
general-purpose I/O pins with their input and output states controlled by
the PD2, PO2, and PI2 registers. All port pins default to high-impedance
mode after a reset. Software must configure these pins after release
from reset to remove the high-impedance condition. All special func-
tions must be enabled from software before they can be used.
Port 3 General-Purpose, Digital I/O Pins with Interrupt Capability. These
port pins function as general-purpose I/O pins with their input and out-
put states controlled by the PD3, PO3, and PI3 registers. All port pins
default to high-impedance mode after a reset. Software must configure
these pins after release from reset to remove the high-impedance con-
dition. All external interrupts must be enabled from software before they
can be used.
No Connection. Not internally connected.
Exposed Pad. For low-current applications (< 10mA of GPIO current,
exclusive of IRTX sink current), these pins can be left unconnected. If
used, they should be connected directly to the ground plane.
