mbed_official 76:aeb1df146756 15 ==============================================================================
mbed_official 76:aeb1df146756 16 [..]
mbed_official 76:aeb1df146756 17 (#) The SDIO clock (SDIOCLK = 48 MHz) is coming from a specific output of PLL
mbed_official 76:aeb1df146756 18 (PLLVCO) througth a fixed divider by 2.
mbed_official 76:aeb1df146756 19 Before to start working with SDIO peripheral make sure that the PLLVCO is
mbed_official 76:aeb1df146756 20 well configured to 96MHz.
mbed_official 76:aeb1df146756 21 The SDIO peripheral uses two clock signals:
mbed_official 76:aeb1df146756 22 (++) SDIO adapter clock (SDIOCLK = 48 MHz).
mbed_official 76:aeb1df146756 23 (++) APB2 bus clock (PCLK2).
mbed_official 76:aeb1df146756 24 PCLK2 and SDIO_CK clock frequencies must respect the following
mbed_official 76:aeb1df146756 25 condition: Frequenc(PCLK2) >= (3 / 8 x Frequency(SDIO_CK)).
mbed_official 76:aeb1df146756 26 (#) Enable peripheral clock using
mbed_official 76:aeb1df146756 27 RCC_APB2PeriphClockCmd(RCC_APB2Periph_SDIO, ENABLE).
mbed_official 76:aeb1df146756 28 (#) According to the SDIO mode, enable the GPIO clocks using
mbed_official 76:aeb1df146756 29 RCC_AHBPeriphClockCmd() function.
mbed_official 76:aeb1df146756 30 The I/O can be one of the following configurations:
mbed_official 76:aeb1df146756 31 (++) 1-bit data length: SDIO_CMD, SDIO_CK and D0.
mbed_official 76:aeb1df146756 32 (++) 4-bit data length: SDIO_CMD, SDIO_CK and D[3:0].
mbed_official 76:aeb1df146756 33 (++) 8-bit data length: SDIO_CMD, SDIO_CK and D[7:0].
mbed_official 76:aeb1df146756 34
mbed_official 76:aeb1df146756 35 (#) Peripheral's alternate function:
mbed_official 76:aeb1df146756 36 (++) Connect the pin to the desired peripherals' Alternate
mbed_official 76:aeb1df146756 37 Function (AF) using GPIO_PinAFConfig() function.
mbed_official 76:aeb1df146756 38 (++) Configure the desired pin in alternate function by:
mbed_official 76:aeb1df146756 39 GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF.
mbed_official 76:aeb1df146756 40 (++) Select the type, pull-up/pull-down and output speed via
mbed_official 76:aeb1df146756 41 GPIO_PuPd, GPIO_OType and GPIO_Speed members.
mbed_official 76:aeb1df146756 42 (++) Call GPIO_Init() function.
mbed_official 76:aeb1df146756 43
mbed_official 76:aeb1df146756 44 (#) Program the Clock Edge, Clock Bypass, Clock Power Save, Bus Wide,
mbed_official 76:aeb1df146756 45 hardware, flow control and the Clock Divider using the SDIO_Init()
mbed_official 76:aeb1df146756 46 function.
mbed_official 76:aeb1df146756 47 (#) Enable the Power ON State using the SDIO_SetPowerState(SDIO_PowerState_ON)
mbed_official 76:aeb1df146756 48 function.
mbed_official 76:aeb1df146756 49 (#) Enable the clock using the SDIO_ClockCmd() function.
mbed_official 76:aeb1df146756 50 (#) Enable the NVIC and the corresponding interrupt using the function
mbed_official 76:aeb1df146756 51 SDIO_ITConfig() if you need to use interrupt mode.
mbed_official 76:aeb1df146756 52 (#) When using the DMA mode
mbed_official 76:aeb1df146756 53 (++) Configure the DMA using DMA_Init() function.
mbed_official 76:aeb1df146756 54 (++) Active the needed channel Request using SDIO_DMACmd() function.
mbed_official 76:aeb1df146756 55 (#) Enable the DMA using the DMA_Cmd() function, when using DMA mode.
mbed_official 76:aeb1df146756 56 (#) To control the CPSM (Command Path State Machine) and send commands to the
mbed_official 76:aeb1df146756 57 card use the SDIO_SendCommand(), SDIO_GetCommandResponse() and
mbed_official 76:aeb1df146756 58 SDIO_GetResponse() functions. First, user has to fill the command
mbed_official 76:aeb1df146756 59 structure (pointer to SDIO_CmdInitTypeDef) according to the selected
mbed_official 76:aeb1df146756 60 command to be sent. The parameters that should be filled are:
mbed_official 76:aeb1df146756 61 (++) Command Argument.
mbed_official 76:aeb1df146756 62 (++) Command Index.
mbed_official 76:aeb1df146756 63 (++) Command Response type.
mbed_official 76:aeb1df146756 64 (++) Command Wait.
mbed_official 76:aeb1df146756 65 (++) CPSM Status (Enable or Disable).
mbed_official 76:aeb1df146756 66 To check if the command is well received, read the SDIO_CMDRESP register
mbed_official 76:aeb1df146756 67 using the SDIO_GetCommandResponse(). The SDIO responses registers
mbed_official 76:aeb1df146756 68 (SDIO_RESP1 to SDIO_RESP2), use the SDIO_GetResponse() function.
mbed_official 76:aeb1df146756 69 (#) To control the DPSM (Data Path State Machine) and send/receive
mbed_official 76:aeb1df146756 70 data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(),
mbed_official 76:aeb1df146756 71 SDIO_ReadData(), SDIO_WriteData() and SDIO_GetFIFOCount() functions.
