Macros | |
| #define | GPIO_UNDEF (0xffffffff) |
| Definition of a fitting UNDEF value. | |
| #define | GPIO_PIN(x, y) ((gpio_t) ((x << 4) | y)) |
| Mandatory function for defining a GPIO pins. | |
| #define | GPIO_MODE(x, y) ((x << 1) | y) |
| Internal macro for combining pin mode (x) and pull-up/down (y). | |
| #define | CONFIG_EFM32_XTIMER_USE_LETIMER 0 |
| Use LETIMER as the base timer for XTIMER. | |
| #define | PROVIDES_PM_LAYERED_OFF |
| CPU provides own pm_off() function. | |
| #define | PM_NUM_MODES (2U) |
| Number of usable power modes. | |
Enumerations | |
| enum | |
| Available ports on the EFM32. | |
| #define | ADC_MODE(x, y) ((y << 4) | x) |
| Internal macro for combining ADC resolution (x) with number of shifts (y). | |
| #define | ADC_MODE_UNDEF(x) (ADC_MODE(x, 15)) |
| Internal define to note that resolution is not supported. | |
