Description
Test Mode Select for JTAG interface. Also used as Serial wire
debug data input/output.
Test Reset for JTAG interface.
Test Clock for JTAG interface. This clock must be slower than
1 /6 of the CPU clock (CCLK) for the JTAG interface to operate.
Also used as serial wire clock.
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. This pin includes
a 20 ns input glitch filter.
Reset status output. A LOW output on this pin indicates that the
device is in the reset state for any reason. This reflects the
RESET input pin and all internal reset sources.
RTC controlled output. This is a 1.8 V pin. It goes HIGH when a
RTC alarm is generated.
Input to the RTC 32 kHz ultra-low power oscillator circuit.
Output from the RTC 32 kHz ultra-low power oscillator circuit.
USB port 2 bidirectional D line.
RTC power supply: 3.3 V on this pin supplies power to the RTC.
3.3 V regulator supply voltage: This is the power supply for the
on-chip voltage regulator that supplies internal logic.
Analog 3.3 V pad supply voltage: This can be connected to the
same supply as V
noise and error. This voltage is used to power the ADC and
DAC. Tie this pin to 3.3 V if the ADC and DAC are not used.
3.3 V supply voltage: This is the power supply voltage for I/O
other than pins in the VBAT domain.
ADC positive reference voltage: This should be the same
voltage as V
error. The voltage level on this pin is used as a reference for
ADC and DAC. Tie this pin to 3.3 V if the ADC and DAC are not
used.
