ADAU1787 registers generated by SigmaDSP tool, not in datasheet

The following registers are generated by the SigmaDSP tool, but not found in the ADAU1787 datasheet.

All have an address > 0xCC00.

Are they useful for development and documented somewhere else?

/* these registers are not documented, are but generated by the SigmaDSP tool */
/* SDSP_MEM_SPEED_CTRL */
/* SDSP_MEM_SLEEP_CTRL */
/* FDSP_MEM_SPEED_CTRL */
/* FDSP_MEM_SLEEP_CTRL */
/* I2C_PAD_CTRL */
/* TEST_PAD0_CTRL */
/* TEST_PAD1_CTRL */
/* ADC01_BIAS_OVERRIDE */
/* ADC23_BIAS_OVERRIDE */
/* TEMP_ADC_BIAS */
/* MBIAS_TEST */
/* FDSP_TEST_MODES */
/* FAULT_DISABLE */
/* ALDO_CTRL */
/* PMU_TEST */
/* DUMMY_SPI_ENABLE */
/* PLLCalculator */
