Does anyone know which pin on the BCM20736S is its RTS pin?

P1 is tied to the WP pin of the embedded EEPROM, so RTS is not available via the PUART on the module. This is why the RTS pin no longer appears as a GPIO option in the datasheet.
CTS should still be available.

Thanks for the link. Did a bit of hunting & still found the documentation was referencing other BCM2073X parts. For a definitive answer it would be nice to know which pin or pins correspond to the PUART_RTS from a document labelled for the BCM20736S.
I've looked through the BCM20736S Technical Reference Manual & extracted the following information. The only reference to an RTS was a timing diagram, no reference to pin allocation. Does this mean the BCM20736S doesn't support PUART_RTS?

from the TRM P1 is described as:
How does the use of P1 as PUART_RTS interact with the WP of the EEPROM? Is the 10K pull-up still a requirement?

10k pull-up is required for P1 of BCM20736S.
I think you can use P1 as PUART_RTS anyway.
But I'm not sure that bleprofile_WriteNVRAM() works properly with it.

is P1 the only Pin that can be used for PUART_RTS on the BCM20736S?
