5.8 TX/RX Data Interface Serial Bus
The AMIS-53000 uses a 3-wire or 4-wire SPI serial data interface to transfer data between the external host controller and the
AMIS-53000. The interface is selected by writing to a register in the AMIS-53000. The DOPT line is undefined in the 3-wire interface.
The 4-wire interface of the AMIS-53000 is designed to be compatible with the definition of a standard SPI interface. The AMIS-53000
can be a slave or master device. The status of the AMIS-53000, master or slave, and the interface mode, read or write, determine the
definition of the DRXTX and DOPT pin’s as outputs or inputs.
