Single-chip 16-bit/32-bit microcontrollers
Description
P0.29 — General purpose input/output digital pin (GPIO).
AD0.2 — ADC 0, input 2.
CAP0.3 — Capture input for Timer 0, channel 3.
MAT0.3 — Match output for Timer 0, channel 3.
P0.30 — General purpose input/output digital pin (GPIO).
AD0.3 — ADC 0, input 3.
EINT3 — External interrupt 3 input.
CAP0.0 — Capture input for Timer 0, channel 0.
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.
