GPIO − General-purpose input/output pin. All GPIOs come up as input after reset.
§
It is highly recommended that V
CCA
be isolated from the digital supply voltage (and V
SSA
from digital ground) to maintain the specified accuracy
and improve the noise immunity of the ADC.
¶
Only when all of the following conditions are met: EMU1/OFF is low, TRST is low, and EMU0 is high
#
No power supply pin (V
DD
, V
DDO
, V
CCA
, V
SS
, or V
SSO
) should be left unconnected. All power supply pins must be connected appropriately for
proper device operation.
