Description

P0.31 — General purpose output only digital pin (GPO)

UP_LED — USB GoodLink LED indicator, it is LOW when device is

configured (non-control endpoints enabled), it is HIGH when the device is not

configured or during global suspend

CONNECT — Signal used to switch an external 1.5 kΩ resistor under the

software control, used with the SoftConnect USB feature

Important: This is an digital output only pin, this pin MUST NOT be externally

pulled LOW when RESET pin is LOW or the JTAG port will be disabled

Port 1: Port 1 is a 32-bit bidirectional I/O port with individual direction controls

for each bit, the operation of port 1 pins depends upon the pin function

selected via the pin connect block, pins 0 through 15 of port 1 are not

available

P1.16 — General purpose input/output digital pin (GPIO)

TRACEPKT0 — Trace Packet, bit 0, standard I/O port with internal pull-up

P1.17 — General purpose input/output digital pin (GPIO)

TRACEPKT1 — Trace Packet, bit 1, standard I/O port with internal pull-up

P1.18 — General purpose input/output digital pin (GPIO)

TRACEPKT2 — Trace Packet, bit 2, standard I/O port with internal pull-up

P1.19 — General purpose input/output digital pin (GPIO)

TRACEPKT3 — Trace Packet, bit 3, standard I/O port with internal pull-up

P1.20 — General purpose input/output digital pin (GPIO)

TRACESYNC — Trace Synchronization, standard I/O port with internal

pull-up

Note: LOW on this pin while RESET is LOW enables pins P1.25:16 to

operate as Trace port after reset

P1.21 — General purpose input/output digital pin (GPIO)

PIPESTAT0 — Pipeline Status, bit 0, standard I/O port with internal pull-up

P1.22 — General purpose input/output digital pin (GPIO)

PIPESTAT1 — Pipeline Status, bit 1, standard I/O port with internal pull-up

P1.23 — General purpose input/output digital pin (GPIO)

PIPESTAT2 — Pipeline Status, bit 2, standard I/O port with internal pull-up

P1.24 — General purpose input/output digital pin (GPIO)

TRACECLK — Trace Clock, standard I/O port with internal pull-up

P1.25 — General purpose input/output digital pin (GPIO)

EXTIN0 — External Trigger Input, standard I/O with internal pull-up

P1.26 — General purpose input/output digital pin (GPIO)

RTCK — Returned Test Clock output, extra signal added to the JTAG port,

assists debugger synchronization when processor frequency varies,

bidirectional pin with internal pull-up

Note: LOW on RTCK while RESET is LOW enables pins P1.31:26 to operate

as Debug port after reset

P1.27 — General purpose input/output digital pin (GPIO)

TDO — Test Data out for JTAG interface
