Flash programming voltage pin. This pin must be connected to
a 5-V supply for Flash programming. The Flash cannot be
programmed if this pin is connected to GND. When not
programming the Flash (i.e., during normal device operation),
this pin can either be left connected to the 5-V supply or it can
be tied to GND. This pin must not be left floating at any time. Do
not use any current-limiting resistor in series with the 5-V supply
on this pin. This pin is a “no connect” (NC) on ROM parts (i.e.,
this pin is not connected to any circuitry internal to the device).
Connecting this pin to 5 V or leaving it open makes no difference
on ROM parts.

Branch control input. BIO is polled by the
BCND pma,BIO
instruction. If BIO is low, a branch is executed. If BIO is not used,
it should be pulled high. This pin is configured as a branch
control input by all device resets. It can be used as a GPIO, if
not used as a branch control input.

Emulator I/O #0 with internal pullup. When TRST is driven high,
this pin is used as an interrupt to or from the emulator system
and is defined as input/output through the JTAG scan.

EMU1/OFF

Emulator pin 1. Emulator pin 1 disables all outputs. When TRST
is driven high, EMU1/OFF is used as an interrupt to or from the
emulator system and is defined as an input/output through the
JTAG scan. When TRST is driven low, this pin is configured as
OFF. EMU1/OFF, when active low, puts all output drivers in the
high-impedance state. Note that OFF is used exclusively for
testing and emulation purposes (not for multiprocessing
applications). Therefore, for the OFF condition, the following
apply:
TRST = 0
EMU0 = 1
EMU1/OFF = 0

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

, V
DDO
, V

, or V
SSO
) should be left unconnected. All power supply pins must be connected appropriately for proper
device operation.
