Test Mode Select Input — This input pin is used to sequence the
JTAG TAP controller’s state machine. It is sampled on the rising
edge of TCK and has an on-chip pullup resistor.
Port D GPIO — This GPIO pin can be individually programmed as
an input or output pin.
After reset, the default state is TMS
Note: Always tie the TMS pin to VDD through a 2.2K resistor if need
to keep on-board debug capability. Otherwise directly tie to VDD

Reset — This input is a direct hardware reset on the processor.
When RESET is asserted low, the device is initialized and placed in
the reset state. A Schmitt-trigger input is used for noise immunity.
The internal reset signal is deasserted synchronous with the
internal clocks after a fixed number of internal clocks.
Port D GPIO — This GPIO pin can be individually programmed as
an input or open-drain output pin.If RESET functionality is disabled
in this mode and the chip can be reset only via POR, COP reset, or
software reset.
After reset, the default state is RESET.

Port A GPIO — This GPIO pin can be individually programmed as
an input or output pin.
ANA0 and CMPA_P2 — Analog input to channel 0 of ADCA and
positive input 2 of analog comparator A.
CMPC_O— Analog comparator C output
When used as an analog input, the signal goes to the ANA0 and
CMPA_P2.
After reset, the default state is GPIOA0.

When used as an analog input, the signal goes to the ANA1 and
CMPA_M0.
After reset, the default state is GPIOA1.
