15.6.2
In the Mode Selection Bits a Read Only can be selected. The Read Only access clears the INT bits that are
selected in the Configuration Select (some interrupt bits show a state, and can not be cleared with a SPI read).
With this SPI command no write access is done to the SBC, and the mode of the SBC is not changed. The
watchdog can also be triggered with a Read Only command.
The Read Only command delivers the information requested with the Configuration Select in the same SPI
command on the SDO pin. As all other SPI commands deliver the requested information with the next SPI
command.
