PN7462 HSU as a Conventional UART

Hi

We are evaluating PN7462 (actually prototyping) for a battery powered reader application. We need PN7462 to do the all NFC related work and then pass on some application level data to another host processor over a Serial UART interface. I am a bit confused if the HSU on PN7462 is meant for some proprietary protocol and/or data only? Could it be used as any generic UART interface - we need to be able to send custom data using custom protocol.

 

The same goes for the I2C. There maybe a requirement later on to use PN7462 I2C as slave for custom data communication with an external MCU. I understand that only one of the I2C, SPI, UART can be used at a time.

 

Thanks
