I/O
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.
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.
P1.28 —
General purpose input/output digital pin (GPIO).
TDI —
Test Data in for JTAG interface.
P1.29 —
General purpose input/output digital pin (GPIO).
TCK —
Test Clock for JTAG interface. This clock must be slower than
1
6
of the CPU clock (CCLK) for the JTAG interface to operate.
P1.30 —
General purpose input/output digital pin (GPIO).
TMS —
Test Mode Select for JTAG interface.
P1.31 —
General purpose input/output digital pin (GPIO).
TRST —
Test Reset for JTAG interface.
USB bidirectional D+ line.
USB bidirectional D
line.
External reset input:
A LOW on this pin resets the device, causing
I/O ports and peripherals to take on their default states, and processor
execution to begin at address 0. TTL with hysteresis, 5 V tolerant.
Input to the oscillator circuit and internal clock generator circuits.
Output from the oscillator amplifier.
Input to the RTC oscillator circuit.
Output from the RTC oscillator circuit.
Ground:
0 V reference.
