CDB3318
2.2 Register Maps Tab
The Register Maps tab provides an easy register-level interface to the on-board devices. Register values
can be modified on a bit-wise or byte-wise basis. To modify a single bit, first select the register by clicking
its position in the register matrix, then click the appropriate push-button for the desired bit. To modify an
entire register, simply enter the register’s new value directly into the register matrix.
Within the Register Maps tab, the CS3318 tab is used to access the CS3318’s internal registers, and the
GPIO tab is used to access the on-board microcontroller outputs used to control the CS3308’s MUTE input
and default I²C address.

The Comm Mode Select box may be used to change the CS3318’s serial communication protocol between
I²C and SPI. The CS3318 will be automatically reset when the communication protocol is changed.
The software is only capable of addressing the CS3318 at its default address. If the CS3318’s individual
address is changed, the software will loose communication with the device until it is reset, thereby returning
to its default address. See the CS3318 datasheet for more information about the device’s individual ad-
dress.
