Buffer Type^a Description
OD
An output that indicates the processor is in
Hibernate mode.
OD
I²C module 0 clock.
OD
I²C module 0 data.
OD
I²C module 1 clock.
OD
I²C module 1 data.
TTL
QEI module 0 index.
TTL
QEI module 1 index.
Power
-
Low drop-out regulator output voltage. This pin
requires an external capacitor between the pin and
GND of 1 µF or greater. The LDO pin must also be
connected to the VDDC pins at the board level in
addition to the decoupling capacitor(s).
No connect. Leave the pin electrically
unconnected/isolated.
