High voltage supply pin. This pin is used as supply for the internal voltage regulator, described in
”Voltage regulator” on page
Internal 10V clamping of VFET voltage for external decoupling.
Digital supply voltage. Normally connected to VREG.
Output from the internal voltage regulator. Used for external decoupling to ensure stable regula-
tor operation. For details, see

Ground.
Port A serves as a low-voltage 4-bit bi-directional I/O port with internal pull-up resistors (selected
for each bit). As inputs, Port A pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port A pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port A also serves the functions of various special features of the Atmel ATmega16HVB/32HVB
as listed in
Port B is a low-voltage 8-bit bi-directional I/O port with internal pull-up resistors (selected for
each bit). As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the ATmega16HVB/32HVB as
listed in
Port C (PC5) is a high voltage Open Drain output port.
