10.5.1.1.3 Continuous Read / Write Operation

The TLV320AIC3106 includes the ability to read/write registers continuously, without needing to provide an address for every register accessed. In SPI mode, a continuous write is executed by transitioning MFP0 (SPI chip select) low to start the frame, sending the first 8-bit command word to read/write a particular register, and then sending multiple bytes of register data, intended for the addressed register and those following. A continuous read is done similarly, with multiple bytes read in from the addressed register and the following registers on the page. When the MFP0 (SPI chip select) pin is transitioned high again, the frame ends, as does the continuous read/write operation. A new frame must begin again with a new command word, to start the next bus transaction.

Note that this continuous read/write operation does not continue past a page boundary. The user should not attempt to read/write past the end of a page, since this may result in undesirable operation.
