1. S: power supply; I: input; O: output using push-pull drivers; PP: I/O using push-pull drivers.
2. The extended DAT lines (DAT1-DAT3) are input on power-up. They start to operate as DAT lines after SET_BUS_WIDTH
3. After power-up this line is input with 50 kOhm pull-up (can be used for card detection or SPI mode selection). The pull-up

Secure digital memory card interface
This section applies to the MicroSD card when used with an adapter.
The secure digital memory card has an advanced 9-pin communication interface (clock,
command, 4 data pins and 3 power supply pins) designed to operate in a low voltage range.
The secure digital card has its nine pins exposed on one side (see
