4 AVMD6210-SWA12- Connector Information
Table 1 shows the module connector pin out for the SWA12. A goal of the design is to have the exact same pin out for
both the Tx and Rx modules. The module function is completely determined by firmware.
The module pins provide the capability to use either SPI slave or I2C slave interfaces – these are mutually exclusive. If an
I2C slave host interface is used GPIOs 2 and 3 can be used for general purpose I/O. In addition, the SPI master port is
brought out to the connector to facilitate direct programming of the module flash memory if required. A single I2S port is
brought to the connector and can be configured to be either a slave or master port. The MCLK pin can be an input or
output to offer optimal flexibility. Likewise the I2S audio pin can be an input or output to implement either audio Tx or Rx.
In addition, there are 5 other GPIOs that can be used exclusively for system features such as pair button, interrupt, LEDs
etc. The reset pin allows for an external device to reset the module but must be driven from an open drain device to avoid
timing issues with the module reset.
Note: the connector pin out is subject to change throughout the development process to optimize the PCB
routing.
