22.5.4 PIN CONTROL REGISTERS
Each GPIO has two Pin Control registers. The Pin Control Register, which is the primary register, is used to read the
value of the input data and set the output either high or low. It is used to select the alternate function via the Mux Control
bits, set the Polarity of the input, configure and enable the output buffer, configure the GPIO interrupt event source,
enable internal pull-up/pull-down resistors, and to enable VCC Emulation via the Power Gating Signals control bits. The
Pin Control Register 2 is used to configure the output buffer drive strength and slew rate.
The following tables define the default settings for the two Pin Control registers for each GPIO in each product group.
