My question is about FTM module.
I'm looking to know the behavior of S32 FTM pin, if the mux is configured as FTM mode (PORT_PCR_MUX), but the FTM is disabled by (ELSB:ELSBA) in CnSC register.
There is a comment from RM in Table 45-5. Channel Modes Selection, in case of ELSB:ELSA = 00:
"Pin not used for FTM—revert the channel pin to general purpose I/O or other peripheral control"
If the mux of the pin is still configured as FTM mode, what is the behavior ?
Do you have further explanation for this comment?
What is the logic state of the pin in this case? (output Low or high?, input or hi-Z )
The corresponding digital input buffer (GPIO_PDIR) is active in all digital functions.
If you don't drive the pin externally and the internal pull devices are disabled (PCRn_PE = 0), the pin is floating.
