29.1. GPIO Pin Special Roles
Not all GPIO ports can be configured as both input and outputs. Given the limited number of GPIO each
pin can assume different functionality based on the software configuration of the ports. The functionality of
each GPIO is described in Table 29.3.
It is important to emphasize the following:


Notes:
GPIO[0] can be used only as input for user application. It can also serve as a crystal oscillator input.
During device NVM programming the programming VPP=6.5V voltage is applied to this pin.
GPIO[5] can be used only as a up to 1mA LED current driver. The LED should be connected directly in
between the GPIO[5] and VCC. In a development system this pin is used as a C2 interface C2CLK. In
the development system the LED has to be isolated from the pin as shown in Figure 34.1 and
Figure 34.2. The LED is disabled during debugging.

1. Can be set as GPIO input only. Special roles are crystal oscillator (XO) and VPP=6.5V NVM
2. Reference clock source for frequency counter.
3. Current mode driver for LED connected directly to VCC supply. GPIO[5] cannot be used for any
4. Optional customer clock clk_out output can be set independently on GPIO[4] and GPIO[6], or on
programming voltage supply during NVM programming.
