+===== GUI Controls =====
+^GUI Control Name^Default Value^Range^Function Description^
+|Max|1| 1 - (Depends on Size of the SPI RAM)|This control specifies the maximum delay supported for the current instance in samples (32-bit word). Maximum value of this is calculated depends on the SPI RAM's configuration. Change in this value requires a re-compilation|
+|Cur|1| 1 - Max|Current delay value |
 \\
 ===== Grow Algorithm =====
-The module support the algorithm growth up to 16. The input pin will be added for each algorithm instance and user has to select the parameter for all the algorithm instances. If parameter is not selected for any of the instance then the module will not update any parameter.
+The module supports grow functionality upto four channels and support multiple instances.
 \\
 \\
 ===== Configurations =====
-The selection of the parameter will be enabled only when the schematic compilation is completed successfully. The user can select the module for which the parameter needs to be updated. After selecting the module, the parameter within the module should be selected for which value should be updated. The value of the selected parameter will be updated with the given input value for each sample once the schematic is downloaded. User can also change the parameter selection when the schematic is downloaded. It will start updating the newly selected parameter once the parameter selection window is closed.

+|Read Instruction (SPI)|3|0-255|Instruction value for a read operation (0x1 for ADI audio devices, typically 0x3 for eeprom/flash)|
+|Write-Enable instruction (SPI)|6|0-255|Instruction value for device write-enable operation|
+Any change in these SPI configuration parameters requires a recompilation.

-The selection window lists the parameters of the modules used in the ADAU145x schematic. It allows user to     select the parameters from DM0 or DM1.
+**Note:**If the Slave Select is 0 and MP0 is used as chip select, no configuration is required in the register controls. Otherwise particular multipurpose pin should be configured act as the slave select in the register window. (Hardware Configuration -> ICx - ADAU145x Register Controls -> MULTIPURPOSE/ AUXADC)

 \\
-The selection window lists the parameters of the modules used in the ADAU144x schematic. It allows user to select the parameters from Coefficient or Nonmodulo data.
+  - Slave Select Channel -> 'Slave Select Channel x'
+  - MPx pin mode -> 'Slave Select for Master SPI port'
+  - MPx pin function -> 'Multipurpose function'

+There is some inconsistency between register control and the 'Default chip/Device Address' in the module. The following table shows the mapping between module's parameter and the register control window.
+^ ' Default chip/Device Address' ^'Slave Select Channel' in the Register control^
+|     1    |    Slave Select Channel 0    |
+|     2    |    Slave Select Channel 1    |
+|     3    |    Slave Select Channel 2    |
+|     4    |    Slave Select Channel 3    |
+|     5    |    Slave Select Channel 4    |
+|     6    |    Slave Select Channel 5    |
