mbed_official 205:c41fc65bcfb4 15 ==============================================================================
mbed_official 205:c41fc65bcfb4 16 ##### GPIO specific features #####
mbed_official 205:c41fc65bcfb4 17 ==============================================================================
mbed_official 205:c41fc65bcfb4 18 [..]
mbed_official 205:c41fc65bcfb4 19 Each port bit of the general-purpose I/O (GPIO) ports can be individually
mbed_official 205:c41fc65bcfb4 20 configured by software in several modes:
mbed_official 205:c41fc65bcfb4 21 (+) Input mode
mbed_official 205:c41fc65bcfb4 22 (+) Analog mode
mbed_official 205:c41fc65bcfb4 23 (+) Output mode
mbed_official 205:c41fc65bcfb4 24 (+) Alternate function mode
mbed_official 205:c41fc65bcfb4 25 (+) External interrupt/event lines
mbed_official 205:c41fc65bcfb4 26
mbed_official 205:c41fc65bcfb4 27 [..]
mbed_official 205:c41fc65bcfb4 28 During and just after reset, the alternate functions and external interrupt
mbed_official 205:c41fc65bcfb4 29 lines are not active and the I/O ports are configured in input floating mode.
mbed_official 205:c41fc65bcfb4 30
mbed_official 205:c41fc65bcfb4 31 [..]
mbed_official 205:c41fc65bcfb4 32 All GPIO pins have weak internal pull-up and pull-down resistors, which can be
mbed_official 205:c41fc65bcfb4 33 activated or not.
mbed_official 205:c41fc65bcfb4 34
mbed_official 205:c41fc65bcfb4 35 [..]
mbed_official 205:c41fc65bcfb4 36 In Output or Alternate mode, each IO can be configured on open-drain or push-pull
mbed_official 205:c41fc65bcfb4 37 type and the IO speed can be selected depending on the VDD value.
mbed_official 205:c41fc65bcfb4 38
mbed_official 205:c41fc65bcfb4 39 [..]
mbed_official 205:c41fc65bcfb4 40 The microcontroller IO pins are connected to onboard peripherals/modules through a
mbed_official 205:c41fc65bcfb4 41 multiplexer that allows only one peripheral’s alternate function (AF) connected
mbed_official 205:c41fc65bcfb4 42 to an IO pin at a time. In this way, there can be no conflict between peripherals
mbed_official 205:c41fc65bcfb4 43 sharing the same IO pin.
mbed_official 205:c41fc65bcfb4 44
mbed_official 205:c41fc65bcfb4 45 [..]
mbed_official 205:c41fc65bcfb4 46 All ports have external interrupt/event capability. To use external interrupt
mbed_official 205:c41fc65bcfb4 47 lines, the port must be configured in input mode. All available GPIO pins are
mbed_official 205:c41fc65bcfb4 48 connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
mbed_official 205:c41fc65bcfb4 49
mbed_official 205:c41fc65bcfb4 50 [..]
mbed_official 205:c41fc65bcfb4 51 The external interrupt/event controller consists of up to 23 edge detectors
mbed_official 205:c41fc65bcfb4 52 (16 lines are connected to GPIO) for generating event/interrupt requests (each
mbed_official 205:c41fc65bcfb4 53 input line can be independently configured to select the type (interrupt or event)
mbed_official 205:c41fc65bcfb4 54 and the corresponding trigger event (rising or falling or both). Each line can
mbed_official 205:c41fc65bcfb4 55 also be masked independently.

mbed_official 205:c41fc65bcfb4 70 configured through "Speed" member from GPIO_InitTypeDef structure,
mbed_official 205:c41fc65bcfb4 71 the speed is configurable: 2 MHz, 10 MHz and 50 MHz.
mbed_official 205:c41fc65bcfb4 72 (++) If alternate mode is selected, the alternate function connected to the IO
mbed_official 205:c41fc65bcfb4 73 is configured through "Alternate" member from GPIO_InitTypeDef structure
mbed_official 205:c41fc65bcfb4 74 (++) Analog mode is required when a pin is to be used as ADC channel
mbed_official 205:c41fc65bcfb4 75 or DAC output.
mbed_official 205:c41fc65bcfb4 76 (++) In case of external interrupt/event selection the "Mode" member from
mbed_official 205:c41fc65bcfb4 77 GPIO_InitTypeDef structure select the type (interrupt or event) and

mbed_official 205:c41fc65bcfb4 96 (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
