SEL_PROC_TAP

Processor Test Controller Select

This pin must be tied low (direct connection to ground is

acceptable) for normal operation.

This pin should only be pulled high when debugging.

SC_ACT/

O12

SmartCard Active LED

This pin can be configured as SmartCard activity LED.

LED_B0/

GPIO1

LED B0

This pin can be configured as a general purpose LED.

GPIO14

(SC_PSNT_N)

IPU

SmartCard Insertion

This pin is designated as the SmartCard card detection

pin and can be left unconnected if the socket is not used.
