SDIO Interface
F5
SDIO_DATA_2
I/O SDIO data line 2. This pin has an internal weak pull-up resistor.
Note: By default, the internal pull-up is enabled, but it can be
disabled via software. The pull-up resistor is forced on for SPI
mode since this pin is unused in that mode.
L6
SDIO_DATA_0/SPI_MISO I/O SDIO data line 0. This pin has an internal weak pull-up resistor.
Note: By default, the internal pull-up is enabled, but it can be
disabled via software.
L5
SDIO_DATA_1/SPI_IRQ I/O SDIO data line 1. This pin has an internal weak pull-up resistor.
Note: By default, the internal pull-up is enabled, but it can be
disabled via software.
L7
SDIO_CLK/SPI_CLK
I
SDIO clock.
K6
SDIO_DATA_3/SPI_CSX I/O SDIO data line 3. This pin has an internal weak pull-up resistor.
Note: By default, the internal pull-up is enabled, but it can be
disabled by software.
K7
SDIO_CMD/SPI_MOSI I/O SDIO command line. This pin has an internal weak pull-up
resistor.
Note: By default, the internal pull-up is enabled, but it can be
disabled by software.
SDIO/SPI weak internal pull-up resistances:
For 1.8V (minimum, typical, maximum): 34 kΩ, 51 kΩ, 86 kΩ
For 2.5V (minimum, typical, maximum): 21 kΩ, 32 kΩ, 54 kΩ
For 3.3V (minimum, typical, maximum): 16 kΩ, 24 kΩ, 37 kΩ
Software programmable SDIO/SPI drive strength options:
For 1.8V: 0.5 mA, 1.0 mA, 1.5 mA, 2.0 mA, 2.5 mA (default), and 3.0 mA
For 2.5V: 1.5 mA, 3.0 mA, 4.5 mA, 6.0 mA, 7.5 mA (default), and 9.0 mA
For 3.3V: 2.0 mA, 4.0 mA, 6.0 mA, 8.0 mA, 10.0 mA (default), and 12.0 mA

I
For normal operation, connect as described in the JTAG
specification (IEEE Std 1149.1). Otherwise, if JTAG is not used,
this pin can be left unconnected (NC) as it has an internal weak
pull-up resistor.
O For normal operation, connect as described in the JTAG
specification (IEEE Std 1149.1). Otherwise, if JTAG is not used,
this pin can be left unconnected (NC). This pin is also muxed
with UART_TX, which can be enabled by software.
