Description
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
Data for transfer
This field contains the data for transfer during a slave receive or
transmit operation. When written the register data is used as transmit
data. When read, this register returns the last data received.
Data is stored until next update, either by a system write for transmit
or by an external master for receive.
