From the spec, We support CSC/I2C master mode, no mention that we can support slave mode.
The CYW43907 has two Cypress Serial Control (CSC2) master interfaces for external communication with codecs, DACs, NVRAM,
etc. The I/O pads can be configured as pull-ups or pull-ups can be installed on the reference design to support a multimaster on an
open drain bus.
Thank you for your supporting.
We already know that 43907 can support a multimaster by your DataSheet.
But customer wants to use the host CPU (ARM) to control 43907 by I2C.
Then host CPU's side is master, and 43907's side is slave.
If they have not slave function, how to control 43907 by I2C?
When they want to use the I2C, did you have some good suggest?

Actually, 43907 is designed as host mcu + wifi mode, so I2C slave mode is not the design as default reasonably.
If customer wants to use 43907 as a device mode totally , suggest to use the interface like SPI which has slave function.
