28.3.1 Pin Configuration

Figure 28.1. Pin Configuration
Note
In addition to setting the pins as either outputs or inputs, the GPIO_Px_MODEL and GPIO_Px_MODEH
registers can be used for more advanced configurations. GPIO_Px_MODEL contains 8 bit fields
named MODEn (n=0,1,..7) which control pins 0-7, while GPIO_Px_MODEH contains 8 bit fields named
MODEn (n=8,9,..15) which control pins 8-15. In some modes GPIO_Px_DOUT is also used for extra
configurations like pull-up/down and glitch suppression filter enable. Table 28.1 (p. 391) shows the
available configurations.

There is no ESD diode to Vdd because if using LCD voltage boost the pin voltage will be
higher than Vdd. Nevertheless there is an ESD protection block against over voltage.
