| + | ===== Support for Multiple Slaves ===== | ||
| + | Multiple external devices can be configured by creating multiple instances of the master control port boot time IO module and selecting appropriate slave select in the configuration parameters. | ||

| + | The sequence of booting up of different slaves can be configured by using the drop down list next to the {{: | ||
| + | {{ : | ||
| + | |||
| + | ===== Support for Different SPI Slave Select Pins ===== | ||
| + | If the device to be programmed is selected through MP0 (the /SS_M pin), no configuration is required in the register controls. Otherwise, the multipurpose pin must be configured to act as the slave select in the Register Window. (Hardware Configuration -> ICx - ADAU145x Register Controls -> MULTIPURPOSE/ | ||

| + | ===== Creating Sequence File for SPI/I2C slave not supported by SigmaStudio ===== | ||
| + | Use the following file and edit for your slave. | ||
| + | <file xml ADAU1361.xml> | ||
| + | <?xml version=" | ||
| + | <ROM IC=" | ||
| + | < | ||
| + | < | ||
| + | <page modetype=" | ||
| + | <action instr=" | ||
| + | <action instr=" | ||
| + | <action instr=" | ||
| + | <action instr=" | ||
| + | </ | ||
| + | </ | ||
| + | </ | ||
| + | |||
| + | Please follow the steps below to edit the XML for your Slave. | ||
| + | * Edit IC, IC_Address and Address_byte_length fields in xml. Please note that IC_Address should be an 8-bit I2C address in decimal format. Address_byte_length refers to the length, in bytes, of the external IC's address space. | ||
| + | <code xml> | ||
| + | <ROM IC=" | ||
| + | </ | ||
| + | * Add your register writes as shown below. | ||
| + | <code xml> | ||
| + | <action instr=" | ||
| + | |||
| + | </ | ||
| + | Please match all the fields as follows. | ||
| + | instr => " | ||
| + | len => Data Length in bytes+ Address_byte_length | ||
| + | addr => Register Address in decimal (not hexadecimal) | ||
| + | Then the value part should have the register values in Hexadecimal. A space should separate each data as shown in the example. | ||
| + | |||
| + | * You can add delays as shown below. | ||
| + | <code xml> | ||
| + | <action instr=" | ||
| + | </ | ||
| + | Delay is in milliseconds (Hexadecimal Format) | ||
