1
RESET
I
Reset Input. Active low. This pin has an internal weak pull-up resistor to REG_DVDD and should
be left unconnected when not in use. For added security and robustness, it is recommended
that this pin be strapped via a resistor to REG_DVDD.
2
GPIO_5/IRQ1/RxD
I/O
General-Purpose Digital IO 5/External Interrupt Request 1 (Active High)/Receive Data for UART
Serial Port. By default and after a power-on reset, this pin is configured as an input. The pin has
an internal weak pull-up resistor and should be left unconnected when not in use.
3
GPIO_6/TxD
I/O
General-Purpose Digital IO 6/Transmit Data for UART Serial Port. By default and after a power-
on reset, this pin is configured as an input. The pin has an internal weak pull-up resistor and
should be left unconnected when not in use.
4
GPIO_7/IRQ4
I/O
General-Purpose Digital IO 7/External Interrupt Request 4 (Active High). By default and after a
power-on reset, this pin is configured as an input. The pin has an internal weak pull-up resistor
and should be left unconnected when not in use.
5
GPIO_8/IRQ5
I/O
General-Purpose Digital IO 8/External Interrupt Request 5 (Active High). By default and after
power-on reset, this pin is configured as an input. The pin has an internal weak pull-up resistor
and should be left unconnected when not in use.
6
TCK
I
JTAG Test Clock. This clock input pin is one of the standard 5-pin JTAG debug ports on the part.
TCK is an input pin only and has an internal weak pull-up resistor. This pin should be left
unconnected when not in use.
7
TDI
I
JTAG Test Data Input. This data input pin is one of the standard 5-pin JTAG debug ports on the
part. TDI is an input pin only and has an internal weak pull-up resistor. This pin should be left
unconnected when not in use.

NC
No Connect. Not internally connected and are reserved for possible future use. Therefore, do
not externally connect these pins. These pins can be grounded, if required.
17, 25, 26
NC
No Connect. Internally connected and are reserved for possible future use. Therefore, do not
externally connect these pins. These pins can be grounded, if required.
10
TDO
O
JTAG Test Data Output. This data output pin is one of the standard 5-pin JTAG debug ports on
the part. TDO is an output pin only. At power-on, this output is disabled and pulled high via an
internal weak pull-up resistor. This pin should be left unconnected when not in use.
