Undocumented memory location - ADAU1761

I noticed that the output files from SigmaStudio include the following function:

SIGMA_WRITE_REGISTER_BLOCK( DEVICE_ADDR_IC_1, REG_NON_MODULO_RAM_1_IC_1_ADDR , R19_NON_MODULO_REGISTERS_IC_1_SIZE, R19_NON_MODULO_REGISTERS_IC_1_Default );

 

This writes 0x0FFC to address 0x40E9.  I don't see anything that documents what address 0x40E9 is in the datasheet.  If this data is not transferred it seems to mess up any Non-Modulo data loading.
