C-bus 400 kHz specification compatible pad. It requires external pull-up to provide an output
Description
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
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.
Analog ground: 0 V reference. This should nominally be the same voltage
as V
3.3 V power supply: This is the power supply voltage for the core and I/O
ports.
Analog 3.3 V power supply: This should be nominally the same voltage as
V
used to power the on-chip ADC(s) and DAC.
ADC reference voltage: This should be nominally less than or equal to the
V
pin is used as a reference for ADC(s) and DAC.
RTC power supply voltage: 3.3 V on this pin supplies the power to the RTC.
