Bus width selection
After checking the bus functional lines, the host must change the bus width configuration
accordingly. This is done by using the SWITCH command to program the BUS_WIDTH byte
in the modes segment of the EXT_CSD register.
The BUS_WIDTH byte is write only.
By default (after power-up or software reset (CMD0)), the contents of the BUS_WIDTH byte
is set to 0x00.
The valid values for this register are defined in
If the value programmed by the host is invalid, the BUS_WIDTH byte remains unchanged
and the SWITCH_ERROR bit is set.
