...the world's most energy friendly microcontrollers

and key registers. All write accesses to the AES module must be 32-bit operations, i.e. 8- or 16-bit

operations are not supported.

2.1.27 General Purpose Input/Output (GPIO)

In the EFM32GG232, there are 53 General Purpose Input/Output (GPIO) pins, which are divided into

ports with up to 16 pins each. These pins can individually be configured as either an output or input. More

advanced configurations like open-drain, filtering and drive strength can also be configured individually

for the pins. The GPIO pins can also be overridden by peripheral pin connections, like Timer PWM

outputs or USART communication, which can be routed to several locations on the device. The GPIO

supports up to 16 asynchronous external pin interrupts, which enables interrupts from any pin on the

device. Also, the input value of a pin can be routed through the Peripheral Reflex System to other

peripherals.

2.2 Configuration Summary

The features of the EFM32GG232 is a subset of the feature set described in the EFM32GG Reference

Manual. Table 2.1 (p. 7) describes device specific implementation of the features.
