#### SDIO/SDMMC pins definition
40+
41+
Since STM32 core v2.6.0, the `PinMap_SD[]` array defined in the `PeripheralPins*.c` has been split per signals:
42+
```C
43+
PinMap_SD_CK[]
44+
PinMap_SD_DATA0[]
45+
PinMap_SD_DATA1[]
46+
PinMap_SD_DATA2[]
47+
PinMap_SD_DATA3[]
48+
PinMap_SD_DATA4[]
49+
PinMap_SD_DATA5[]
50+
PinMap_SD_DATA6[]
51+
PinMap_SD_DATA7[]
52+
/* Only for SDMMC */
53+
PinMap_SD_CKIN[]
54+
PinMap_SD_CDIR[]
55+
PinMap_SD_D0DIR[]
56+
PinMap_SD_D123DIR[]
57+
```
58+
59+
This allows to define the SDIO/SDMMC pins to use instead of using all the pins defined in the old array.
60+
By default, if no pins are explicitly defined, the first one from each array is used.
61+
62+
* To redefine the default one, use the following macros:
63+
64+
* `SDX_D0`
65+
* `SDX_D1`
66+
* `SDX_D2`
67+
* `SDX_D3`
68+
* `SDX_CMD`
69+
* `SDX_CK`
70+
71+
* Only for `SDMMC`:
72+
* `SDX_CKIN`
73+
* `SDX_CDIR`
74+
* `SDX_D0DIR`
75+
* `SDX_D123DIR`
76+
77+
* or redefine the default one before call of `begin()` of `SDClass` or `init()` of `Sd2Card`, use the following methods:
78+
79+
* `setDx(uint32_t data0, uint32_t data1, uint32_t data2, uint32_t data3)`
80+
* `setCK(uint32_t ck)`
81+
* `setCK(PinName ck)`
82+
* `setCMD(uint32_t cmd)`
83+
* `setCMD(PinName cmd)`
84+
85+
* Only for `SDMMC`:
86+
* `setCKIN(uint32_t ckin)`
87+
* `setCKIN(PinName ckin)`
88+
* `setCDIR(uint32_t cdir)`
89+
* `setCDIR(PinName cdir)`
90+
* `setDxDIR(uint32_t d0dir, uint32_t d123dir)`
91+
* `setDxDIR(PinName d0dir, PinName d123dir)`
92+
93+
*Code snippet:*
94+
```C++
95+
Sd2Card card;
96+
card.setDx(PE12, PE13, PE14, PE15);
97+
card.setCMD(PB_14); // using PinName
98+
card.setCK(PB15);
99+
card.init();
100+
```
101+
or
102+
```C++
103+
SD.setDx(PE12, PE13, PE14, PE15);
104+
SD.setCMD(PB14);
105+
SD.setCK(PB_15); // using PinName
106+
SD.begin();
107+
```
108+
109+
* or using the `begin()` of `SDClass` or `init()` of `Sd2Card` methods:
110+
111+
* For `SDIO`:
112+
* `SDClass`:
113+
* `begin(uint32_t data0, uint32_t data1, uint32_t data2, uint32_t data3, uint32_t ck, uint32_t cmd)`
114+
* `begin(uint32_t detect = SD_DETECT_NONE, uint32_t data0 = SDX_D0, uint32_t data1 = SDX_D1, uint32_t data2 = SDX_D2, uint32_t data3 = SDX_D3, uint32_t ck = SDX_CK, uint32_t cmd = SDX_CMD, uint32_t ckin = SDX_CKIN, uint32_t cdir = SDX_CDIR, uint32_t d0dir = SDX_D0DIR, uint32_t d123dir = SDX_D123DIR);`
