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 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.
Port C is a 5-bit high voltage Open Drain bi-directional I/O port.
High voltage output to drive Charge/Discharge FET. For details, see
Filtered positive/negative input from external current sense resistor, used to by the Coulomb
Counter ADC to measure charge/discharge currents flowing in the battery pack. For details, see
