Reset

Writing a 1 to this bit places the device in reset. The device

remains in reset until a 0 is written to this bit. All of the

configuration registers return to their default values.

LSB first

Serial port communication, LSB or MSB first.

0 = MSB first.

1 = LSB first.

Address increment

Controls address increment mode for multibyte register access.

0 = address decrement.

1 = address increment.

SDO active

4-wire SPI select.

0 = SDIO operates as a bidirectional input/output. The SDO signal

is disabled.

1 = SDIO operates as an input only. The SDO signal is active.

SDO active

This bit is a mirror of Bit 4 in Register 0x0000.

Address increment

This bit is a mirror of Bit 5 in Register 0x0000.

LSB first

This bit is a mirror of Bit 6 in Register 0x0000.

Reset

This bit is a mirror of Bit 7 in Register 0x0000.
