Which channels of the ETPU cannot be used as PWM input in MPC5634

Hi

  When I configured eTPU27 channel as PWM input in MPC5634,I found the IPS bit in SCR register of eTPU27 was 0 all the time.The CHIP manual indicates that eTPU27 has IO function,when select PA.However, the PWM input is not detected through debugging monitoring.The ETPU reference manual is found in the second picture,in which I found that ETPU was not connected with Pin.Why is the chip reference manual different from the ETPU manual?Are there differences in understanding between the two places?Does this etpu manual apply to other MPC5XXX chips?Please reply the soonest possible.

    Best wishes!

It seems screenshot from eTPURM is only related MPC55xx device where eTPU modules is used. MPC56xx use eTPU2 module.

I guess you forgot setup below:

The eTPU2 reference addendum can be found at https://www.nxp.com/files-static/32bit/doc/ref_manual/ETPURMAD.pdf.
