7.2 Register Definitions
The complete register setup consists of 24 registers of 8 bits each, as shown in the table below. All registers are
preconfigured with the default values and do not have to be programmed by the user if no changes in the setup
are required.
The registers C, E, I and J can be used to configure the XE3005 and XE3006 differently than the default setup.
The registers L, M, N, O, P are related to the Sandman
function available in the XE3006.
