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 k 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). Standard I/O port
with internal pull-up.
TRACEPKT0 — Trace Packet, bit 0.
P1.17 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
TRACEPKT1 — Trace Packet, bit 1.
P1.18 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
TRACEPKT2 — Trace Packet, bit 2.
P1.19 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
TRACEPKT3 — Trace Packet, bit 3.
P1.20 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
TRACESYNC — Trace Synchronization.
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). Standard I/O port
with internal pull-up.
PIPESTAT0 — Pipeline Status, bit 0.
P1.22 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
PIPESTAT1 — Pipeline Status, bit 1.
P1.23 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
PIPESTAT2 — Pipeline Status, bit 2.
P1.24 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
TRACECLK — Trace Clock.
P1.25 — General purpose input/output digital pin (GPIO). Standard I/O port
with internal pull-up.
EXTIN0 — External Trigger Input.
