Datasheet
3.5.4
Address Pointer
All data writes and reads are accessed from the current address pointer. In both Bi-directional mode
and Full Duplex mode, the Address pointer is automatically incremented following every read
command or every write command.
The address pointer will return to 00h after reaching FFh.
3.5.5
SPI Timeout
The CAP1128 does not detect any timeout conditions on the SPI bus.
3.6
Normal SPI Protocols
When operating in normal mode, the SPI bus internal address pointer is incremented depending upon
which command has been transmitted. Multiple commands may be transmitted sequentually so long
as the SPI_CS# pin is asserted low. Figure 3.3 shows an example of this operation.
