Hi ,

Its unclear from the datasheet for the BCM20732S, which pin is the RTS pin ?.

I see that CTS is pin 30 and in older datasheets RTS was pin 25.

Does a UART RTS pin exist for the BCM20732S.

Thanks

Mark

Upon doing some research internally on the subject of flow control, it appears that flow control 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.

Please accept our apologies for the confustion.

I agree that this is confusing as the datasheet states that P25/P1 is tied to the WP pin of the embedded EEPROM.

However, the WICED Smart Hardware Interfaces document seems to imply that P1 is available for the Optional RTS function: WICED™ Smart Hardware Interfaces
