Configuration Register Notes
1. Important: All changes to the internal settings of the ISD5008 are synchronized with the load of
Configuration Register 1. A command to load Configuration Register 1 immediately transfers the
input data to the internal settings of the device and the changes take place immediately at the end
of the command when SS goes HIGH. A load to Configuration Register 0 sends the new data to
