PA0 and PA6 contain two different Timer functions, a timer input and a complementary
timer output. Both of these functions require the same GPIO configuration, the selection
between the two is based on the TIMER mode. For more details, see the
page 68.
The Port C pins provide a sinked current output, capable of driving an LED without
requiring an external resistor. The output sinks current at programmable levels, 3 mA,
7 mA, 13 mA and 20 mA. This mode is enabled through the LED Control registers.
For proper function, the LED anode must be connected to V
GPIO pin.
Using all Port C pins in LED drive mode with maximum current may result in excessive
total current. See the
current for the applicable package.
On the 20- and 28-pin devices, the Port D0 pin shares function with a bidirectional reset
pin. Unlike all other I/O pins, this pin does not default to GPIO function on power-up.
This pin acts as a bidirectional input/output open-drain reset with an internal pull-up until
the user software reconfigures it as a GPIO PD0. When in GPIO mode, the Port D0 pin
functions as output only, and must be configured as an output. PD0 supports the high drive
feature, but not the stop-mode recovery feature.
For systems using a crystal oscillator, the pins PA0 and PA1 are connected to the crystal.
When the crystal oscillator is enabled, the GPIO settings are overridden and PA0 and PA1
are disabled. See the
In the 20- and 28-pin versions of this device, any pin, which shares functionality with an
ADC, crystal or comparator port is not 5 V-tolerant, including PA[1:0], PB[5:0] and
PC[2:0]. All other signal pins are 5 V-tolerant and can safely handle inputs higher than
V
tor.
