The Port C pins provide a current sinked output capable of driving an LED without requir-
ing an external resistor. The output sinks current at programmable levels of 3mA, 7mA,
13mA and 20mA. This mode is enabled through the Alternate Function sub-register AFS1
and is programmable through the LED control registers.
For correct 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. Refer to the
current for the applicable package.
On the 8-pin product versions, the reset pin is shared with PortA2, but the pin is not lim-
ited to output-only when in GPIO mode.
On the 8-pin version of this device only, the Debug pin shares function with the PortA0
GPIO pin. This pin performs as a general purpose input pin on power-up, but the debug
logic monitors this pin during the reset sequence to determine if the unlock sequence
occurs. If the unlock sequence is present, the debug function is unlocked and the pin no
longer functions as a GPIO pin. If it is not present, the debug feature is disabled until/
unless another reset event occurs. For more details, see
For systems using a crystal oscillator, PA0 and PA1 are used to connect the crystal. When
the crystal oscillator is enabled (see
the GPIO settings are overridden and PA0 and PA1 are disabled.
All six I/O pins on the 8-pin devices are 5V-tolerant, unless the programmable pull-ups are
enabled. If the pull-ups are enabled and inputs higher than V
excessive current flows through those pull-up devices and can damage the chip.
