Data

The host data register I/O location (DATA) provides access to the host transmit and receive data buffers. Reading valid data or writing data to be transmitted can be successfully done only when SCL is held low by the host (STATUS.CLKHOLD is set). An exception is reading the last data byte after the stop condition has been sent.

Accessing DATA.DATA auto-triggers I2C bus operations. The operation performed depends on the state of CTRLB.ACKACT, CTRLB.SMEN and the type of access (read/write).
