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.
