| mbed_official | 235:685d5f11838f | 15 | ##### GPIO Peripheral features ##### |
| mbed_official | 235:685d5f11838f | 16 | ============================================================================== |
| mbed_official | 235:685d5f11838f | 17 | [..] |
| mbed_official | 532:fe11edbda85c | 18 | Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each |
| mbed_official | 532:fe11edbda85c | 19 | port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software |
| mbed_official | 532:fe11edbda85c | 20 | in several modes: |
| mbed_official | 532:fe11edbda85c | 21 | (+) Input mode |
| mbed_official | 532:fe11edbda85c | 22 | (+) Analog mode |
| mbed_official | 532:fe11edbda85c | 23 | (+) Output mode |
| mbed_official | 532:fe11edbda85c | 24 | (+) Alternate function mode |
| mbed_official | 532:fe11edbda85c | 25 | (+) External interrupt/event lines |
| mbed_official | 235:685d5f11838f | 26 | |
| mbed_official | 532:fe11edbda85c | 27 | [..] |
| mbed_official | 532:fe11edbda85c | 28 | During and just after reset, the alternate functions and external interrupt |
| mbed_official | 532:fe11edbda85c | 29 | lines are not active and the I/O ports are configured in input floating mode. |
| mbed_official | 532:fe11edbda85c | 30 | |
| mbed_official | 532:fe11edbda85c | 31 | [..] |
| mbed_official | 532:fe11edbda85c | 32 | All GPIO pins have weak internal pull-up and pull-down resistors, which can be |
| mbed_official | 532:fe11edbda85c | 33 | activated or not. |
| mbed_official | 235:685d5f11838f | 34 | |
| mbed_official | 532:fe11edbda85c | 35 | [..] |
| mbed_official | 532:fe11edbda85c | 36 | In Output or Alternate mode, each IO can be configured on open-drain or push-pull |
| mbed_official | 532:fe11edbda85c | 37 | type and the IO speed can be selected depending on the VDD value. |
| mbed_official | 235:685d5f11838f | 38 | |
| mbed_official | 532:fe11edbda85c | 39 | [..] |
| mbed_official | 532:fe11edbda85c | 40 | All ports have external interrupt/event capability. To use external interrupt |
| mbed_official | 532:fe11edbda85c | 41 | lines, the port must be configured in input mode. All available GPIO pins are |
| mbed_official | 532:fe11edbda85c | 42 | connected to the 16 external interrupt/event lines from EXTI0 to EXTI15. |
| mbed_official | 532:fe11edbda85c | 43 | |
| mbed_official | 532:fe11edbda85c | 44 | [..] |
| mbed_official | 532:fe11edbda85c | 45 | The external interrupt/event controller consists of up to 23 edge detectors |
| mbed_official | 532:fe11edbda85c | 46 | (16 lines are connected to GPIO) for generating event/interrupt requests (each |
| mbed_official | 532:fe11edbda85c | 47 | input line can be independently configured to select the type (interrupt or event) |
| mbed_official | 532:fe11edbda85c | 48 | and the corresponding trigger event (rising or falling or both). Each line can |
| mbed_official | 532:fe11edbda85c | 49 | also be masked independently. |
