S32K Uart CTS_B Input State

[guys_fr]

Hello,

CPU S32K144 / S32K148 family.

Is it possible to read the CTS_B input state ? I would like to know if the transmitter is in flow controlled ON/OFF. From the register list (Uart), the modem signal state are not listed. It is not mention if GPIO input is still valid if the pin is in Uart mode.

Thanks, Guy

Hi guysansoucy,

Whenever a pin is configured in any digital pin muxing mode, the input buffer for that pin is enabled allowing the pin state to be read via the corresponding GPIO Port Data Input Register (GPIO_PDIR).

Best Regards,
Robin
